[...] But currently it's not possible to install 2 (or more) packages with the same name. So a user can't have guile 2.0 and guile 1.8 in the same profile. The same thing with python: there is no ‘python2’ package. Both python packages have “python” name and can't be installed in the same profile, as far as I understand. -- Alex
