The Darwin development community has done a great job bringing "X" to OS X. Rootless X works great. There are nice Window Managers available. I thought this would be a realtively straight forward build with a fully functional X-windows install, but my attempts to build Perl Tk look like they failed for realtively simple reasons (looked like a recursion in an atempt to link a shared library). I can't find it. Apparently I am simpler than the bug. The author acknowledged the problem and said a fix would come out, but no sign. I was hoping someone here may have figured a way around this problem.
