Done! And it comes up, even though I had to set
 EMACSLATEPACKAGES=/usr/local/lib/xemacs
so that it would pick up my package path.

I also had to change configure to use -pthread instead -mthreads:

*** configure.orig      2008-01-31 10:42:27.000000000 +0100
--- configure   2008-01-31 12:23:12.000000000 +0100
