Which can be "fixed" by this one (a better fix would be to patch ghc-pkg
and/or cabal to use libdir/libsubdir for shared libraries the same way
as for static libraries and to drop the $arch-$os-$compiler patterns):

And indeed. After a few iterations of fixing plists of hs-ports (after
the dynlibdir patch above), with pkg_delete -a in between, I ran into
build errors like this one:
===> Configuring for hs-vector-0.12.0.3
ld.so: ghc: can't load library 'libffi.so.1.2'
Killed
The ghc binary was linked against our system libffi (from devel/libffi),
and after the pkg_delete -a and a restart of dpb, this was missing. So
I'll now try to build ghc using our libffi instead of the bundled one.
Ciao,
Kili
