So the real problem was that was not placed in compat when the 
version number was bumped.

There was a bump in libc, it just happened much earlier.  The remainder of the 
libraries were bumped shortly before 6.0-RELEASE, but not after the release 
once it became -STABLE.  Libraries also have ABI dependencies on other library 
revisions -- i.e., if an API changes in libc, and libypclnt depends on the old 
version of the API, it needs to use the old libc.

Could you grab a from RELENG_5 and stick it in your compat 
tree and see what happens?
