hi,

on ubuntu-studio 12.04 / 64bit i get this error when using readanysf~ in pd (no problem compiling the external):

readanysf~.pd_linux: undefined symbol: bgav_select_track readanysf~ ... couldn't create

i have installed: libgavl1 1.2.0-4 libmerlin-avdec1 1.1.0

It seems to be a linking order problem. IOhannes already fixed it in the Debian git repository, but I haven't had time (or was too lazy) to notify upstream or push out a new package.

This is the patch written by IOhannes, that needs to be applied to Makefile:
