Where do you have xterm installed?  Is it at /usr/bin/xterm?  If not you
can edit the line in src/pm/mpirun_rsh.h that defines XTERM to the
correct path of xterm.  You can then run make && make install inside the
src/pm directory to just rebuild mpirun_rsh.

I'm not sure where the garbage values are coming from here.  Perhaps
fixing the xterm issue will help here to.
