[Vorbis] need help compiling libvorbis with msys

[Merick]

I'm trying to compile libvorbis from svn using mingw/msys, like so:

autogen.sh --prefix=/mingw && make && make install

But configure quits with this error message:

./configure: line 12230: syntax error near unexpected token `OGG,'
./configure: line 12230: `PKG_CHECK_MODULES(OGG, ogg >= 1.0, 
HAVE_OGG=yes, HAVE_OGG=no)'

(I've already installed ogg without any problems)
