# depending ports using CABAL tend to install into locations as
# lib/Foo-${FooVersion}/ghc-${MODGHC_VER}, so they need the exact

# and include a package registration file in
# ${PREFIX}/lib/ghc/package.conf.d (you'll still have to add the
# necessary @tag ghc-pkg-recache to your PLIST by hand).
# Add "nort" if the port doesn't depend on the GHC runtime. This will
# also turn off the default "hs-" prefix for PKGNAME.
# If "nort" is not added, MODGHC_PACKAGE_KEY may be set to the 'package
# key' of the library built and will be added to SUBST_VARS.
# Finally, set it to or add "hackage" if the distfiles are available on
# hackage.haskell.org.
