My gwc and libsndfile versions are the same as yours so this is a bit odd...

Is the libsndfile install new? Maybe you just need to run ldconfig.

Another thing to try is to find the place in configure where the sndfile version
is checked and comment it out but if configure can't find sf_open in -lsndfile
then the final link probably won't either.

I haven't groked the ladspa plugins yet either! You might try sox which
has more explicit documentation and examples about the compress effect.
