Yes, as in whether install dir is made under /usr/lib or /usr/lib/ghc-<version>/ or whatever. So really this is a request for a "--libdir" option to setup? In some cases --prefix may be sufficient, but not if there is both an executable and libraries in a package for example.
--libdir is a good idea.
Personally I would like to see ghc libraries at least installed under ghc's libdir since their ABI depends on the version of ghc they are built with, ie typically under $libdir/ghc-$ghc_version/ rather than $libdir.
You mean by default, without using the --prefix flag? That seems pretty reasonable.
Yep. Actually if this were the default, I probably wouldn't need --libdir much at all. :-)
I'm not keen for libraries to install in ghc's libdir by default. I'd like to keep GHC's choice of libdir and its layout private to GHC, I don't see the need for other installers to depend on it. By all means make the default package libdir something like $(prefix)/lib/$(package)-$(version)-ghc$(ghcversion). Cheers, Simon

Ok, I understand your concerns I think. An alternative approach I suppose would be to officially endorse installing under ghc's libdir - by actually including say a "packages/" directory there too.
By all means make the default package libdir something like $(prefix)/lib/$(package)-$(version)-ghc$(ghcversion).
That should be fine too, or even "$(prefix)/lib/$(package)-$(version)/ghc-$(ghcversion)" say. Well as long as there is a reasonable default. :) Jens
