Why is ghc looking for version 2.1.0.1 of Parsec?

Hi all, Does anyone know what may be causing ghc to be looking for such an old version of Parsec, here? $ ghc -o libami.so -shared -dynamic -package parsec -package dsp -package arrows -lHSrts -L/usr/lib/ghc-7.0.3/ -lm -lffi -lrt AMIParse.o AMIModel.o ami_model.o AMIModel_stub.o ApplicativeParsec.o ExmplUsrModel.o MaybeT.o Filter.o /usr/bin/ld: cannot find -lHSparsec-2.1.0.1-ghc7.0.3 Thanks, -db
