Re: Cabal and installing packages.

I think it can all be done from a client side program. As cabal provides dependencies, and compile/install scripts it can simply download from Hackage and call the scripts. It sounds like the client could be quite simple, using the HTTP client libraries, then a set of system calls to run the scripts... But I see what you are saying too, a program to convert a cabal-package into say an ebuild for gentoo. A small problem is gentoo's emerge does not pass parameters to the scripts, so you would have to have an ebuild for every haskell package. Keean. Gabriel Ebner wrote:

I find that debian/gentoo etc do not have all the packages available for say perl, and it is nice to have a consistant interface on any platform...

In such cases I think it's better to provide a way to make native packages. E.g. if you want to install some obscure perl module under gentoo, you can just type in g-cpan.pl Some::Obscure::Module, and after a few minutes a bunch of proper native packages will have been installed.

The best thing about g-cpan.pl is that it uses existing packages if possible. So if e.g. dev-perl/LibXML has been patched to work with gcc-3.4 and the package you want to install depends on LibXML, you couldn't install it using CPAN but you could using g-cpan.pl.
