For failed builds, the build page gives access to the whole build tree,
which often provides useful clues.  Here, ‘config.log’ on Darwin reads
this:

  configure:13019: checking for alloca
  configure:13056: gcc -o conftest  -g -O2       -L/usr/X11/lib conftest.c  
-lX11   >&5 
  ld: library not found for -lX11

Indeed, earlier, there is:

  checking for X... libraries /usr/X11/lib, headers 

which is wrong (should be something under /nix/store.)

I think I’ve fixed it by passing ‘--x-libraries’ and ‘--x-includes’ to
‘configure’ but we’ll have to wait for the Darwin build result.

In passing, I added GnuTLS, GTK+, D-Bus, libtiff, and others as
dependencies of Emacs on GNU/Linux (some of these libs do not currently
build on non-GNU platforms so I did not enable them there.)

Thanks,
Ludo’.
