I am hitting this problem:

guix$ ./pre-inst-env guix package -i python-2.7.10
The following package will be installed:
   python       2.7.10  /gnu/store/4bs4mx6xyx0jx9827vmmbxyhjln7cmcv-python-2.7.10

(...)

the symlink points to a symlink:

ls -l /gnu/store/4bs4mx6xyx0jx9827vmmbxyhjln7cmcv-python-2.7.10/share/man/man1/*
