make: *** [alsa.o] Error 1

!!! ERROR: the make command did not complete successfully.

!!! Since this is a critical task, ebuild will be stopped.

!!! emerge aborting on  /usr/portage/media-sound/sox/sox-12.17.1.ebuild .

This happens because it tries to find alsa-0.5.X headers.  This probably means
that sox does not support alsa 0.9.X.

I've committed ebuild for the new version (12.17.3), in which I disabled alsa
support.  But at least it should compile and install for everyone.

Thanks for the report.
