I have just committed a dev-haskell/wxhaskell-0.6 ebuild to the Gentoo
CVS, so it should propagate within the next hour. I had it lying
around for some time now, but never got around to actually adding it.
It is tested on exactly one machine right now, but there seems to be
request for it -- so please test and provide feedback, also if it works
fine.

You can just specify multiple URI's in SRC_URI, and all of them get
downloaded and unpacked by default. As Daan pointed out, in the case
of wxhaskell, it's not needed though, as the source distribution
contains everything to build the documentation.

addwrite for the installation process is not an option. Usually, some
combination of patching, setting prefix, or being lucky and have
DESTDIR, helps.

Should not be a problem. You could probably modify the Makefile and
send the patch to Daan. I'm sure he will consider to apply it.

I have added the library flags needed to link in the wx-gl libaries.
I hope it actually still works with a non-opengl-enabled version
of wxGTK, I haven't tried that.

Best,
