Sounds very much like you don't have the pkg-config development
package which contains the pkg-config autoconf macros. autoconf will
just pass through strings that it doesn't recognize into the final
configure shell script. This will often result in syntax errors in
configure. Do you get any output from 'grep PKG_CHECK' aclocal.m4'?
