You can use ldd.

In practice, however, pretty much all software nowadays depends on  
shared libraries, so it's reasonable to do a "pkg_delete -a" after  
upgrading to a new major version of FreeBSD, and then reinstall all  
of the ports you use once you've finished upgrading.  Run "pkg_info"  
before the upgrade and keep track of this output to help you remember  
what ports you've got installed...
