If you see this:

==> Validating source files with md5sums...
libmpeg3-1.8-src.tar.bz2 ... Passed
libmpeg3.pc ... FAILED


make sure you replace libmpeg3.pc's md5 sum in the new pkgbuild
with the output from

md5sum libmpeg3.pc

new pkgbuild

Name: libmpeg3
Description: Decoder of various derivatives of MPEG standards
Version: 1.8.2
Requires:
Conflicts:
Libs: -L${libdir} -lmpeg3 -lpthread -la52
Cflags: -I${includedir}

I could build this only after changing

make DESTDIR=$startdir/pkg install || return 1

to

make DST=$startdir/pkg install || return 1

Otherwise it couldn't read the directory and tried to install to /usr/bin directly.
