 I can build this package on 8.99.1 on NetBSD/amd64.

 I will take a look at it - I'd tend to guess a script bug in this case
 (the updated shell is just stricter as to what is legal than it used
 to be - though the old version never "worked" (whatever that means here.)

 I have observed this same failure (same package) on i386-8.0_BETA and
 on amd64-8.99.1 (although it may not have picked up the very latest
 changes as Kamil reports success).

 It needs bash to configure, the script contains ...

         if test ${#osx_arch_array[@]} -gt 1 ; then

 which is never going to work with /bn/sh.   Previous versions of /bin/sh
 would have just let that slide by, and done almost anything, but almost
 certainly not what the author intended.

 On NetBSD it most likely does not matter, as we're not OSx and so I'd assume
 that code is never actually executed. but on other systems it does.

 I'll leave it to whoever maintains the package to decide whether to simply
 make it use bash, or to patch this line into oblivion on systems that aren't
 OSx.

 It does have (since a while):
 CONFIG_SHELL=		bash

 I wonder whether it'd make sense to just pullup all the /bin/sh changes
 to 8.0_BETA (and some others). we know it works now, I can build it on
 8.99.1 /bin/sh, but apparently not on 8.0_BETA.

 Then someone who understands pkgsrc ought to work out why that is not
 working (because you clearly would not be getting errors from /bin/sh
 if bash were being used.)

 Sorry, no, it definitely does not work now (the shell in current).  It
 limps by, but there are several problems.   Everything that has been
 changed recently that is safe to pull up has been.   I am hoping to commit
 a bunch more fixes quite soon now, but I need to verify that I am not
 making it even worse first (I hope not, but ...)   From what I have been
 seeing recently I'm actually surprised that sh (and not just with my recent
 changes, though some of the recent breakage is all my fault) works as well
 as it does - there is some "so wacky it us unbelievable" code in there
 (and it has been that way a very long time.)

 But, all that said the change that affected ilmbase (barfing on bash syntax)
 is deliberate (though we could change the way it is implemented, as I 
 suggested in a very recent message on tech-userlevel) and, apart doing what
 was postulated there, which would hide this particular case of bashness,
 I think, nothing else that has happened recently, or is going to happen, will
 make that error go away.

 If you can build ilmbase on current (and it is using sh as the shell to
 run the configure script) then something else is broken...

 ps: I should make clear, that for this one, I have not attempted to
 build the package, I just saw the error message in the PR, and read
 the configure script to see why that might happen, so I do not actually
 know that it is not normally using bash as the shell for the configure
 script - is there perhaps some way to override that setting which might
 explain why some people seem able to build this, and others cannot?

 Installed the latest 8.0_BETA from nyftp (201706131110Z) on amd64,=C2=A0
 and here I can compile the package as well. Anything was changed?


 Is this an issue that manifests itself only on arm?

 No, it was not only on arm.  I experienced it on amd64-current and
 i386-8.0_BETA using pkgsrc-2017Q1.

 The problem is due to a 'bash'-ism in the configure script which slipped
 through earlier revisions of NetBSD's 'sh'.  After the corrections and
 tightening by kre, NetBSD's 'sh' properly choked on it.

 In pkgsrc-HEAD "graphics/ilmbase" has been changed to explicitly use
 'bash' to run its "./configure" scripts.  If you update at least that
 package to HEAD it should configure and build properly.  It does for me.

 There is a pending pull-up to pkgsrc-2017Q1 which includes these
 changes, but it hasn't been committed.  For myself, I just updated
 that package to HEAD.
