Problem running X11 on PPC Mac

[Deborah Goldsmith]

This problem pops up sometimes for all sorts of open source software  
(try Googling _printf$LDBLStub), and can be due to mixing modules  
compiled by gcc 3.3 and gcc 4.0, and/or due to failure to link with - 
lSystemStubs.

I've had good luck using X11 with GHC if I launch it first, and run  
GHC from inside Xterm rather than Terminal. That way you don't need  
to fiddle with DYLD_LIBRARY_PATH. I haven't tried it on PPC, though,  
just Intel. I'll try it at work tomorrow.

You might want to do "gcc_select" and see which version of gcc is the  
default on your system, though is likely not the issue since you had  
problems with the binary distribution.
