[Nix-dev] How to actually get rid of things from the nix-env -qs list?

Which one is active? That's what priorities are about, those who
have higher priorities will be linked first. In your case both will have
.py files, so in fact its likely that one is active

Need source? nix repository -> buildenv.pl should contain what you're
looking for.

How to get rid? I wonder why those packages contain a space?

usually nix-env -e drops them, if this doesn't work (due to the space -
I'm unsure) you can try the rollback features (nix-env) and file a bug
report.
