Ah, that’s an issue with the ‘configure’ script of Zsh now.

I’d recommend looking at how that tcsetpgrp check is implemented, to see
what makes it think it doesn’t work.  In particular what does
‘config.log’ report about this test?

This may be due to the chroot build environment, which could be lacking
something Zsh expects (see
<http://www.gnu.org/software/guix/manual/guix.html#Setting-Up-the-Daemon>
for details.)

Note that bash.scm is relatively complex, because Bash has a limited
‘configure’ interface; hopefully you can do something simpler here.

The ‘license’ field should reflect the license of what gets installed.
So if build-time scripts are GPL, that doesn’t matter here.  But please
do skim over the license headers to make sure they’re all under that
X11-style license.

‘let*’ introduces a ‘configure-flags’ local variable, but it’s not used
after that.  So you can remove that ‘let*’ form altogether, and instead...

... you can add an ‘arguments’ field (info "(guix) Defining Packages"):

  (arguments '(#:configure-flags '("--with-tcsetpgrp")))

In the build log, search for ‘configure flags’, and you’ll notice that
--with-tcsetpgrp is now passed (and I guess this should solve the
problem above?)

My guess is that Zsh doesn’t use Readline nor Texinfo, but please check
its documentation to see what’s needed.

Please wrap lines below 80 characters, and don’t use tabs (see “Coding
Style” in the ‘HACKING’ file.)

Hope this helps!
