This could be a useful package! Do I need to set any more environment
variables in my .bashrc? So far, I have
export PATH=$HOME/.guix-profile/bin:$PATH
export LIBRARY_PATH=$HOME/.guix-profile/lib
export CPATH=$HOME/.guix-profile/include
export MANPATH=$HOME/.guix-profile/share/man:/usr/share/man
export PKG_CONFIG_PATH=$HOME/.guix-profile/lib/pkgconfig:/usr/lib/pkgconfig:/usr/lib/x86_64-linux-gnu/pkgconfig
export PYTHONPATH=$HOME/.guix-profile/lib/python2.7/site-packages
export PERL5LIB=$HOME/.guix-profile/lib/perl5/site_perl
export XDG_DATA_DIRS=$HOME/.guix-profile/share


When I do a "./configure" of mpc, none of the standard headers are recognised;
I obtain something like:
