nam-1.0a7?

[K Sun <ksun@essex.ac.uk>]

Hello,
  I try to install nam-1.0a7, but I meet problems.
There is nothing wrong with my compiling.
However, when I run it, it does not open any windows but display the 
following text: ( the whole text is in the attached file).
I really need help. I do not know why there is such a mismatch and how 
to slove it.
My environment is RedHat 5.2.

regards,

Sun Kai
