I had to rebuild the kernel since I need SCTP support, which is
not included in the default config.  Therefore I can run r252304
without INVARIANTS and INVARIANT_SUPPORT. I'm able to make and
install the devel/cvs port. However, when trying to build the
databases/db42 port (required by the svn port), I get:

...
