Hello Olivier

If you need to compile namd then you should download the source files from
the CVS repository. There have been many improvements since namd2.5 was

You should also get the source for fftw, tcl, and the plugins and compile
those for your machine. ia64 is for intel itaninium processors not athlon
opterons. So no suprise in that error.

Finally, if you are compiling namd, have you already compiled charm++?
Did it go smoothly?
