[arch-haskell] packaging the haskell platform: another shot

[Thomas Girod]

Ok, I think the title of my mail is misleading, and the PKGBUILD too :)

Are you referring to cabal2arch ? if it is the case, I am aware of its
existence, and how it is used to submit pkgbuilds on AUR, but can it
handle the haskell-platform ?

Right now, the HP needs alex=2.3.2 but only alex=2.3.1 is available in
community. Same goes for haddock=2.7.2 required, but haddock=2.6.0 given
by ghc or the AUR package. (I find this one extra weird - if the new HP
is based on ghc-6.12.1, why does it ask for haddock-2.7.2 rather than
2.6.0 ?).

I might be wrong, but the HP's cabalized version looks like a
meta-package calling for the installation of a list of dependencies. And
we all know it doesn't translate well to Arch because of three reasons:

- one version of a package on a system,
- one version of a package on the official repositories,
- one version of the pkgbuild on the AUR.

For these reasons, I was wondering if a haskell-platform package bundling
everything with the right version, depending only on ghc would be the
way to go.

Then, the bleeding-edge stuff could be handled separately within the
AUR, thanks to the cabal2arch automatization process.

Anyway, maybe I'm just the master of the obvious - and if so, please
tell me !
