I don’t know if I’m missing something, but when I type ‘matplotlib’ at
the prompt, I get:

--8<---------------cut here---------------start------------->8---
/gnu/store/g4m8q73cq4lym3v1ag7pnk5zv49mdifs-python-matplotlib-1.4.2/lib/python3.4/site-packages/matplotlib-1.4.2-py3.4-linux-x86_64.egg/matplotlib/backends/backend_gtk3.py in <module>()
     19 except ValueError:
     20     raise ImportError(
---> 21         "Gtk3 backend requires the GObject introspection bindings for Gtk 3 "
     22         "to be installed.")
     23 

ImportError: Gtk3 backend requires the GObject introspection bindings for Gtk 3 to be installed.
--8<---------------cut here---------------end--------------->8---

This may well be related to <http://bugs.gnu.org/20765>: Because Guix
has incomplete dependency information, it might GC some of the things
that these eggs refer to, and so things may or may not work depending on
whether they have been GC’d.

WDYT?
