I've been there, too, before.

Are you sure you need Compiler supporting files etc. on a
machine with a CF card ? Especially compiler directories
from older releases ? (probably not)

in /usr/libdata, perl is the culprit (Check /usr/libdata/perl5/i386-openbsd )
If, and only if you don't have any 3rd part perl scripts, you
can think about cleaning up there. Well, probably most 3rd party
perl scripts will work anyways (but test that !)

Also, if you really have compXX.tgz installed, you most likely
can remove old versions of all static libraries in /usr/lib/
