>Description:

I created a Fedora Core 8 instance in Amazon's EC2, then fetched the latest pkgsrc tarball
and extracted it.  After bootstrapping, I tried to build misc/screen, but it failed saying
that no suitable termcap library was found.

The reson for that appears to be that this image does not by default provide the
ncurses-devel rpm.

If this is needed, then maybe bootstrap should detect this and complain?

Otherwise, it would be nice if misc/screen could just pull in devel/ncurses
or whatever it may need instead of leaving the user guessing what packages
he needs to install.

>How-To-Repeat:
	Install Fedora Core 8 without any -devel packages.
	download pkgsrc
	bootstrap
	cd misc/screen
	bmake

 Does enabling the ncurses option (screen uses the options framework,
 see "bmake show-options") help any?  It seems that it would add the
 ncurses package dependency via buildlink...

 Thanks,

 No. Termcap is optional and should stay that way. E.g. with
 FETCH_USING=fetch, no termcap is required for the infrastructure,
 as well as most packages.

 On Haiku (no builtin curses, termcap, terminfo),
 ncurses from pkgsrc is used automatically in misc/screen.
 I don't know why it does not work on Linux.

 But yes, pkg-options for screen is strange,
 because selecting curses type but include termcap.buildlink3.mk.
 and overwrite user settable variable in Makefile of pkg is bad idea.

 This PR should probably have the synopsis renamed to:

 default termcap options not set appropriately on linux


 I just boostrapped pkgsrc on:

 Gentoo 4Q2009
 Ubuntu 9.10 Karmic Base
 Fedora Core 8

 Neither appears to have gotten a functional pkgsrc -- they all three
 bail out when building tnftp with an error message that 'no usable
 termcap' was found.

 I had to manually install using whatever package management system the
 host provides a suitable termcap library.

 I thought pkgsrc would be smart enough to figure out that no termcap is
 present and pull in something?  Even if not, it'd be nice it would make
 a suggestion as to what the innocent user should do, such as setting
 certain options if those are possible to rectify the situation.
