Ed,
From your email it looks like you are having difficulty getting past the ./configure on Fltk. Is that correct?
I'm not familiar with the Ubuntu distro, but I believe it is based on Debian. Your path to the X11 libraries is either different or the libraries are missing. I think it is more likely to be a path problem.
Assuming that the problem is during the pre-compile for Fltk, try looking at the output of
./configure --help
for more infor on the various parameters that can be passed to the configure script.
Can anyone else who is familiar with Ubuntu help Ed?
