This includes Zack Weinberg's patch to fix tests w/ guile-3.0, which
I've only applied for 3.0.
But in the course of spending a while to get the ebuild working with
two impls and only patching one, I found that 2-2 was clearly not cared
for upstream anymore as I hit two different issues and one of them
had an unreplied-to patch on the ML, so I gave up. Just declare compat
w/ 3-0 and worry about older later for this version on the offchance
someone requests it.
