With commit 5924080, ‘guix package --install’ reports environment
variables that needs to be defined, using information from
‘native-search-paths’.

For example, if you install GCC and a C library, it will tell you to set
CPATH=$HOME/.guix-profile/include and
LIBRARY_PATH=$HOME/.guix-profile/lib, unless the environment variables
are already defined appropriately.

Also, ‘guix package --search-paths’ lists environment variables that
need to be defined, regardless of their current value.

Hopefully that will help avoid common mistakes when using Guix.

Comments welcome!
