=== python-gudev ===

i have problems packaging python-gudev:

gudevmodule.c:19:23: fatal error: pygobject.h: No such file or directory

but looking at the exports (nix-env -i python-gudev -K; source env-vars) i can see:

-I/nix/store/lqsihhkhl7rhr18x7qiviihyp2byc5gw-pygobject-2.27.0/include

but in that folder there is only pygtk-2.0 folder:

ls -la /nix/store/lqsihhkhl7rhr18x7qiviihyp2byc5gw-pygobject-2.27.0/include

pygtk-2.0/

so in that folder i find:

ls -la /nix/store/lqsihhkhl7rhr18x7qiviihyp2byc5gw-pygobject-2.27.0/include/pygtk-2.0/

pyglib.h pygobject.h

=== the problem ===

as discussed in [http://old.nabble.com/Python-3-to22076291.html#a22119842] and quoting [https://nixos.org/repos/nix/nixpkgs/trunk/pkgs/development/python-modules/pygobject/default.nix]

# All python code is installed into a "gtk-2.0" sub-directory. That

# sub-directory may be useful on systems which share several library

# versions in the same prefix, i.e. /usr/local, but on Nix that directory

# is useless. Furthermore, its existence makes it very hard to guess a

# proper $PYTHONPATH that allows "import gtk" to succeed.

so how should i package python-gudev then? the source for python-gudev (which produces the above error) can be found at [https://github.com/NixOS/nixpkgs/blob/master/pkgs/development/python-modules/python-gudev/default.nix]
