`guix environment` launches a new shell. It's possible to get unexpected
problems if you set environment variables in .bashrc, which is sourced
when launching interactive shells, rather than .bash_profile, which is
only sourced for login shells. This is why it's generally recommended to
set environment variables only when launching login shells.

I'm not sure what happened with lispf4 but that is one way that `guix
environment` can be broken.

You might also try the --pure and --container options to `guix
environment`, since they achieve greater degrees of isolation from the
rest of your system.
