I guess you are looking at a wrong place.
The fix must be coincident :)

Basically alsa-driver (and kernel) compilation doesn't use any
user-space library, so libpath is irrelevant.  The only important
location is the kernel source tree and its build stub.  If these
aren't set up properly, such an error (version mismatch or so) may
happen.

Note that sound_register_special() and co aren't defined in the ALSA
driver, but it's defined in sound_core.c in the kernel.
