I am running -ldd on a executable and I am missing links to a bunch of: libTK**.so files such as: libTKGeomBase.so.11 => not found (0) libTKG3d.so.11 => not found (0) libTKG2d.so.11 => not found (0) libTKMath.so.11 => not found (0) I've searched quite a bit and can't find where those files are located. What's going on, how do I link against them?
