Hi,

I can't seem to be able to run the downloaded NAMD2 binaries (e.g.
charmrun) on our Scyld cluster.

The main problem seems to be that libbproc.so.2 is not found at runtime
(see output from ldd below).
I found the libbproc.so.2 library in /usr/lib64/, but adding it to the
LD_LIBRARY_PATH doesn't help...

"file" shows that "charmrun" is 32-bit while the "libbproc.so.2.2.5"
file that I found on my system is 64-bit. Could that be a problem? If
so, where can I find a 32-bit library "libbproc.so.2"??

Thanks in advance for any help or advice!!

Vio

PS: I am also including some info below about the system:
