I'd guess that you have managed to get alsa-lib linking against
something that doesn't exist or is unreadable.

Check the permissions on /usr/lib/alsa-lib/libasound_module_pcm_pulse.so
and also that ldd doesn't report any files not found.   If they are all
found, check the permisisons on all of them.

Also, the file in question is 32 bit.   Hopefully that is the intention :)

That's just general linux stuff, there may be specific alsa reasons why
it's not working.
