unison 2.27.57 does not compile

[gavin@…]

I'm currently running unison 2.13 with x11 variant, and the failure happens during an upgrade. I brought my macports system fully up to date last week, with the exception of unison of course :) I'm running Mac OS 10.4.11, fully up to date, with Xcode 2.4.1.

This port has not worked for a long time. I thought that maybe it was a transient problem, but it's been around for a few months now.

Thanks!

Unison builds if I disable the x11 variant, but fails with it.
