Well in that case you managed to somehow install a 6.x binary on there 
(not compat6x), which is now being linked to 7.0 binaries (this should 
never happen in a correctly functioning system).  Either rerun 
portupgrade -fa, or use pkg_which on the binaries and libraries that are 
giving problems to try and track down which need to be reinstalled.
