At this point I must conjure the semi-regular reminder that "cross-platform homebrew" already exists in the form of Gentoo Prefix. It's got years of work behind it, it's heavily tested, and other people do the work for you -- all we'd have to do is put the desired versions of stuff in a text file. Even that work is done in the form of sage-on-gentoo. So we'd just need to package it up along with some build instructions in a form that users can follow. But lmonade is pretty good at that. We might need to make some adjustments, but the proof-of-concept is there and a lot of the hard work is already done. If you survived the git migration it would seem like a piece of cake. We'd get to remove the package management features from sage, and it would eliminate Volker's best friend the LD_LIBRARY_PATH hack. We would still be installing the universe from scratch, but at least we'd be doing it right. It's also a big step towards getting distros to package sage. -- You received this message because you are subscribed to the Google Groups "sage-devel" group.
