Have you loaded patch 3229 (or its predecessor, 3138)? All
backwards-compat loading was broken without it.

Don't bother with the symbolic links; they are so you can compile
using the most current version. pfdFindConverterDSO() determines
which version to link [based on its own version], but before patch
3138, it was not parsing the version string properly, so runtime
linking of loader DSOs from the compat libs was broken.
