Kraken: clean compile for me, Jeff had issues he's testing now The problem appears to be entirely in my setup. If you have a complex bashrc/profile/whateverrc you might consider moving it out of the way before attempting to install the raft. According to the main femhub guy (Ondrej), this is a SAGE bug, which he is pursuing with their team. Once my bashrc is moved aside, raft works for me too.
OS X: No tests yet, but I'd love it if someone would run this (my laptop doesn't have enough space right now for scratch) Again, setup aside, this builds perfectly. I've played with the notebook, and I can say with some certainty that this is a powerful tool, especially for working remotely. Being able to connect to a webnotebook via ssh port tunneling is awesome.
I would emphasize that if you have any problems installing the raft, I would move any shell config files aside and try again. This seems to solve every problem I've had.
Thanks, Matt. It looks like you've picked a winner with this one.
