[gentoo-user] dev-haskell/{cabal,haxml} -- runaway memory hog

In a "routine" upgrade, I get the following message from several
haskell components:

 * The package dev-haskell/cabal is not correctly installed for
 * the currently active version of ghc (6.8.2). Please
 * run ghc-updater or re-emerge dev-haskell/cabal.

So I tried running ghc-updater, and it hangs emerging haxml by
gradually absorbing all available CPU time, memory, and swap,
eventually the oom killer kills firebird, and eventually I realize
something is going on and kill ghc-updater.

Emerging haxml directly repeats the greedy performance, and when I
kill it, it gives me this message:

 * The 'prerm' phase of the 'dev-haskell/haxml-1.13.2' package has failed
 * with exit value -1. The problem occurred while executing the ebuild
 * located at '/var/db/pkg/dev-haskell/haxml-1.13.2/haxml-1.13.2.ebuild'.
 * If necessary, manually remove the ebuild in order to skip the execution
 * of removal phases.

What the heck is going on here, and how do I manually remove haxml?  I
know nothing of haskell; it is merged only because I use darcs.  The
ebuild mentioned is short and has no "prerm" anywhere in it.

This happens on both a ~x86 machine and a ~amd64 machine.
