My mono-2.pc file contains:

prefix=${pcfiledir}/../..
exec_prefix=${pcfiledir}/../..
libdir=${prefix}/lib
includedir=${prefix}/include/mono-2.0
sysconfdir=/etc

Name: Mono
Description: Mono Runtime
Version: 3.2.8
Libs: -L${libdir}  -lmono-2.0  -lm -lrt  -ldl -lpthread
Cflags: -I${includedir} -D_REENTRANT

And I think "Libs:" is fundamental here.
