well, in a sense you've distributed it to yourself, as opposed to using
a binary distribution where all these packages are rebuilt by someone
else and distributed to you.

no, but my point was a binary OS would re-compile everything multiple
times on some super-server of theirs before you download and try it.
Hence in that case you're the user, not the distributor. In Gentoo's
case you're the user AND the distributor, and 99.9% of the time you
don't need to recompile the universe to end up with a working system.
I'm sure that there is some magic package that just needs to be
re-merged that would fix the issue for you, but I'm sure you've spent
enough time on it, so I'm not suggesting you try :)
