Thanks all of you for being help me on this installation problem.

I tried the way as Jerry suggested. I install the 'vacpp' under my
home directory (i.e: /Users/bo), and the 'namd2' is in the directory
of ' /Users/bo/MD/NAMD/NAMD_2.6b1_MacOSX-PPC'. Then add the path to
where namd2. Here is how I did:

[mriv209-01:~] bo% setenv
But I got the message saying;
tcsh: DYLD_LIBRARY_PATH: Undefined variable
I am not good at the unix system, and confused on how to define the
DYLD. Do I do something wrong? Can you help me to fix this probelm? 
According to vaccp instruction, one needs to deinstall any XL C++ beta
or evaluation run-time packages before installing this run-time
environment.  And I don't know how do this. Does this cause the above
errors, or just I didn't set the path in the right way?
Your advices will be very appreciated.
