See the Autoconf documentation. The AM_PATH_ALSA macro is present in alsa-lib's alsa.m4, on a normal Linux system that is almost always installed, but this is not true for Gentoo/FreeBSD. Please add the alsa.m4 file to the patches tarball, and pass the path of the directory where it's extracted to AT_M4DIR="" .
Fixed, thanks Diego
