Dear Lee,

Xleap often causes problems with the compilation since it requires users to
have the X11 (or Xorg in Fedora) development libraries installed. Often only
the regular (non-development) libraries are present and so Ld returns that
it cannot find -lXt. In your case, however, it knows where libXt is but
claims it is incompatible. I have never seen this error before but I suspect
that it is due to a mismatch in the library versions on your system. I would
try installing the latest version of the X11 and X11 development libraries
that are available for your system and then try compiling leap again. You
can compile leap on it's own by doing cd $AMBERHOME/src/leap and typing
make. Leap is the last thing to be built during the amber installation so
everything should be fine.

All the best
