Milter-greylist

I just upgraded my system from Redhat 8 to Fedora Core 4 ... while
rebuilding milter-greylist I encountered the following error:

gcc -o milter-greylist milter-greylist.o pending.o sync.o conf_yacc.o
dump_yacc.o conf.o autowhite.o dump.o spf.o acl.o  -lresolv -lnsl

Any suggestions?

Thanks!
