portsclean should never touch anything out of /usr/local/and base gcc
should not depend on anything in /usr/local. I'd suspect that setting an
environmental variable such as PORTSDIR might cause this, but that seem
unlikely to have happened without a serious intent.

Is it possible that you are not running the base gcc? ('which gcc' and 'gcc
-v') It should be in /usr/bin and the version for a recent current
should be 4.2.1 20070719.

Is it possible that the portsclean was merely coincidental? Could
something else have happened at about the same time?

As far as recovery goes, what does 'locate libgcc_s.so show? You should
have it in /lib, but there might be another copy around. If that fails,
you can try finding a copy on some other system; a current system of
about the same age as yours so that it will have the same gcc.

Good luck!
