That's a point were I think I should chip in some info. When sage moved to gap 4.5+ I was in pain making a new ebuild for sage-on- gentoo. Initially I was just installing the full gap instead of a trimmed version. Installation takes ages. I have now trimmed things a little bit but it still take ages - but still an improvement.
I had to very quickly blacklist xgap, removing it altogether. In gap 4.5.x it would automatically load when gap was started in sage and cause sage to hang. It took us a little while to pinpoint it. https://github.com/cschwan/sage-on-gentoo/issues/189 in particular https://github.com/cschwan/sage-on-gentoo/issues/189#issuecomment-12587392 Installing the rest had an effect on a couple of doctests if I remember correctly but nothing dramatic.
