Based on the No xauth message....are you behind a firewall? This can
block xleap but not cause problems with tleap (since there are no
graphics that have to be driven).

The seg fault may be unrelated to the warnings.
Try these to examine phase space:
Run tleap.
Give details for the platform actually running leap.
Get a stack trace via
gdb `which teLeap` core.{pid}

The seg fault occurs along with the color and font conversion error
messages every time I try to start xleap. Tleap seems to be working fine
so far.
I also get the message: ''No xauth data. Using fake authentication date
for X11'' forwarding if thats relevant. Would setting a display number
with setenv like I would do if I telnet in possibly be of help?
