Actually, the error described here on #guix
(https://gnunet.org/bot/log/guix/2017-04-06#T1346052) might be the one I
had:

checking how to run the C preprocessor... /lib/cpp” -> configure: error. 

It seems that --pure solved it, which might be an alternative solution.
But anyway it looks like there are a few corner cases for which just
running 'guix environment guix' won't work.
