Hi,

I removed '#:phases' from 'arguments' and added '#:configure-flags':

  (arguments `(#:configure-flags '("--disable-modular-tests"
                                   "--disable-rebuilds")))

Now './pre-inst-env guix-build -K glib' fails with the following errors:

/tmp/nix-build-2ihs5vivxkm0b7v6p7g5h6pqrwz3c1fj-glib-2.34.drv-2/glib-2.34.3/libtool: line 1102: ldconfig: command not found

[...]

AFAICT, the problem is the lack of 'python' in Guix.

Here is a corresponding snippet from Nixpkgs:

# * Make it build without python
#     Problem: an example (test?) program needs it.
#     Possible solution: disable compilation of this example somehow
#     Reminder: add 'sed -e 's@python2\.[0-9]@python@' -i
#       $out/bin/gtester-report' to postInstall if this is solved

  buildNativeInputs = [ perl pkgconfig gettext python ];

Is it possible to solve this without 'python'?
