libghc6-x11-dev dying during package install

I upgraded from Feisty to Hardy beta yesterday. Through synaptic tried to install libghc6-x11-dev. I used to have an installed copy I think but I don't think it still is after the upgrade.

It failed with the following in the summary:
E: /var/cache/apt/archives/libghc6-x11-dev_1.4.1-1_amd64.deb: subprocess new pre-removal script returned error exit status 1
