Yea, some packages are pretty picky but portage has gotten a lot better
with a lot of things in the past couple years.  I know people complain
about a lot of hacks in portage but the end result leaves us with a
system that should boot at least.  That said, if something looks weird,
it's best to ask.  It never hurts.  It also never hurts to have buildpkg
set in make.conf either.  oooooops factor.

Yea, if you bork something, logging out can be a bad thing.  Never
happened here but just in case.  Glad to throw a little sunshine on your
day.  It was 20 F here last night.  Has been the last few nights and I
have psoriasis.  I'm ready for summer now.
