Is this still the case?

I think this should be fixed since python38-3.8.1nb1 via:

cvs rdiff -u -r1.2 -r1.3 pkgsrc/lang/python38/Makefile
cvs rdiff -u -r1.3 -r1.4 pkgsrc/lang/python38/distinfo
cvs rdiff -u -r1.2 -r1.3 pkgsrc/lang/python38/patches/patch-configure

(and also pkgsrc-2020Q1 has that.)

 Now it fails everywhere - on NetBSD 7, 8, 9, all architectures:

 Thanks for the quick feedback! (I think that's actually unrelated to
 the reported PR)

 If you are using `/usr/local' as PREFIX, can you please try to add:

  SUBST_NOOP_OK.findlib=  no

 in lang/python38/Makefile:158 (after `SUBST_SED.findlib+= ..')
 and let us know if that fixes this and the original issue?
 (if that's the case feel also free to commit it!)

 Unfortunately, it doesn't fix it for /usr/local, but you're right that it 
 works if LOCALBASE is unset.

 How that fails if LOCALBASE is set?

 (I think `SUBST_NOOP_OK.findlib= no' is needed in order to have a
 possible noop for the `findlib' subst class (that's completely legit if
 `/usr/local' is LOCALBASE/PREFIX) and it would be nice to possibly
 figure out and fix all problems present :))

 Sorry, I meant:

  SUBST_NOOP_OK.findlib=  yes

 With this, python38 compiles with PREFIX set to /usr/local/

 Thanks!

Confirmed fixed, thanks John for the PR and the feedbacks.

The SUBST-related problem reported in the last days should be now
fixed as well on all lang/python* packages.
