craft workaround for gentoo which allows them to generate package.conf file but not register about cabal HOT 5 CLOSED

(Imported comment by @dcoutts on 2006-01-09)

Yeah, that pretty much sums it up.

At the moment we use this nasty hack:

sed -i 's:ghc-pkg:/usr/bin/true:' .setup-config
./setup register || die "setup register failed"
if [[ -f .installed-pkg-config ]]; then
    do-something-with .installed-pkg-config
fi

This is obviously relying on the implementation and not on any spec. So if we can make a proper way of getting the package conf file then that'd be great.

If we're going to do something, we should do it for the next major release
