Probably:

	LOC_CHECK_LIBS(geos,GEOSGeom_createLinearRing,GEOS,$GEOS_LIBS,GEOS_LIBS)

Your original problem appears to be that you don't have a compatible
version of GEOS installed. It's compiling okay, so it looks like the
headers are compatible but the library isn't. Maybe a problem with
32-bit and 64-bit libraries?
