This is because your shell initialization code (e.g. to set up the
prompt) refers to lesspipe.  You can ignore this or remove the fancy
initialization.

That’s because “--pure” resets the PATH; that’s by design.  The only
problem you have is that your Guix is located elsewhere.  But why do you
need Guix itself inside of an environment to build Guix?

The point of using “guix environment --pure guix” is only to enter a
clean environment containing everything you need to build Guix from
source.  So once you’re inside of this environment you can run the
bootstrap and configure scripts, and run make to compile the sources.

To *use* that Guix you just built you need to use “./pre-inst-env guix”
from the source directory.

This defeats the purpose of using “--pure” as these directories contain
all sorts of things on a foreign distro, so you lose control over the
environment.
