[PD] Ann external source or 64-bit build?

Tue Apr 12 01:24:25 CEST 2022

Try running "sudo ldconfig" and see if that resolves it. If not, do a
sanity check by copying libfann.so.2.2.0 to the fann directory and make a
libfann.so.2 symlink to it there. It's a temporary hack, but if you do that
it really should load properly in Pd. If even that doesn't work, I'm
stumped!
