Two modules w/ different instances of same lib causes crash

My extension (plexsso.so) is dymanically linked with a library. That library (libplexsso.so) is a statically linked collection of libs including a custom version of Heimdal Kerberos (libkrb5.a). I have found that if another module is linked with the stock Heimdal (e.g. pgsql.so dynamically in this case) some symbol mixing occurs and the application crashes. Can two modules use different instances of the same library? Before I go try to become an expert in linking and the Linux loader can anyone give me advice as to how to I might workaround (for Linux at least)?
