can't load plugin libmusepack_decoder

I downloaded moc 2.5.0 and compiled it on Salixos 14 (32 bit). Everything went fine. Only thing I changed was directory prefix, from '/usr/local' to '/usr'. I launched moc and received this error,
can't load plugin libmusepack_decoder
moc runs and everything else works fine but this message is bugging me. I've made sure that required dependencies are fulfilled. I've checked and made sure that ffmpeg, musepack-tools, libmpcdec and taglib are installed. I've also checked '/usr/lib/moc/decoder_plugins' directory and libmusepack related '.so' and '.la' files are there. Any clues as to what could be wrong? Thanks!

Did the plugin compile ok? Maybe you have some old version lying around in /usr/lib/moc/decoder_plugins?

You can also check linking dependencies by ldd /usr/lib/moc/decoder_plugins/libmusepack_decoder.so

You can also try to run MOC in debug mode (mocp -D) and see if logs mocp_[client,server].log contain anything useful.

You can also try to run 2.6a1. If anything, it should be more stable than the stable version ;)

Yes all the plugins compiled without errors. No old version in '/usr/lib/moc/decoder_plugins'. I removed moc, checked '/usr/lib' and there was nothing related to 'moc' and next I compiled moc 2.6a1. Compilation and installation went smoothly without any error. I started moc and the same "can't load plugin libmusepack_decoder" error appeared again.
Here is the result of ldd /usr/lib/moc/decoder_plugins/libmusepack_decoder.so,

I'm completely perplexed! Any fresh ideas?

Everything seems OK (although mocp_server_log could have some additional data). I suppose that there is no error reported also in /var/log/messages?

I compiled moc without musepack decoder cause I don't have a single '.mpc' file in my collection and solving this problem was beyond my capabilities. Anyways keep up the great work you guys have been doing with moc. All the best for future releases!
Cheers!!!
