Debian/Ubuntu does a little different because they split Bacula in  
dynamic loadable parts to use the same main binaries with .so modules  
for different databases. In /usr/lib/bacula/ you can find the modules  
used and they include libpthread.so, so you are done.

If you have done an inplace upgrade from 10.04 carefully check your  
database schema and index. As far as i remember there was a (Ubuntu)  
bug regarding Bacula database when doing OS upgrade.

Also have a look here:
