Doh!! No it's still not working using pre1. Tried the compile as a
straight ./configure, make, make install, and also using aclocal, and friends
prior to ./configure. Both times I used --enable-arch=native. Output below
from starting it on command line.

I've attached the history file for the compile. Maybe something will stand
out.

By the way, I built 0.12.0beta4 on the same machine on a Kubuntu Intrepid
install, and phasex works ok on that.

Also, make uninstall only removes the phasex binary, and
leaves /usr/local/share/themes folder, and /usr/local/share/phasex folder,
and contents.
