Good to know it works.
It will appear in the build help page. :-) But it probaby should appear
if you type:
./build charm++ mpi-linux help
which lists all build options supported specific to mpi-linux.
pthreads is not a recommended way of building charm, it is a workaround
with possibly lower performance. However luckily it is not quite an
issue for NAMD.
