Problem using TeX formatting in labels SOLVED

Hello,

Thanks very much to everyone who helped me with this issue. I found
my LaTeX path by doing echo $PATH in a terminal window, and then
adding this line to the x11 path in my bashrc file,
PATH=/usr/local/teTeX/bin/powerpc-apple-darwin-current:$PATH; export PATH
My plots (labels included) look fine now.

Thanks again,
Adrian
