Yes, I’m feeling the pain with my i686 netbook.

The way I see it, having very large modules like (gnu packages python)
is not desirable anyway.  So we won’t get around distributing package
definitions.  If we can get a fix for Guile soon that’s great, but we
should begin moving packages independent of that.

Okay, I’ll get started with splitting haskell.scm.  I’ll prepare one
patch for each target module.

Okay.  I’ll leave that task for someone else, because I don’t think I
can do more than haskell.scm today.
