Hi - The Makefile.PL in revision 8877 (perhaps eariler revisions too) needs the following 'patch' (sed) to recgonize hs-plugins:
sed -i -e "s/'-package'/0, '-package'/" Makefile.PL This adds a '0' argument to try_compile (run = 0); otherwise ghc is compiled with: ghc plugins --make -v0 -o ... rather than: ghc -package plugins --make -v0 -o ... -- Aloha => Beau;
