Peformer has some functionality to perform basic interference tests. However
these tests are only between bounding volumes <-> bounding volumes, bounding
volumes <-> segements. For a more general geometry you have to resort to
specialized libraries like QCollide, ICollide or Rapid. I use Rapid ansd it work
for me, if heard other people who use ICollide and are satisfied with it.

RAPID : http://www.cs.unc.edu/~geom/OBB/OBBT.html
ICollide : http://www.cs.unc.edu/~geom/I_COLLIDE.html
QCollide : http://www.cs.hku.hk/~tlchung/collision_library.html (no source !!)
