I don't think it's something "wrong" with your files, really, but it is
incompatible with the way 'guix environment' currently operates.

I took another look at nix-build to see how they do things.  They create
a bashrc file in a temporary directory and run bash (or whatever
$NIX_BUILD_SHELL is) with the '--rcfile' flag so that the user's bashrc
isn't used.  We could do something similar, but right now I don't have
any reason to believe that all shells accept an '--rcfile' option, so it
could easily break other setups.
