LAM: How to uninstall all the lam-mpi installations that may exist in a computer

Dear all,

I have recently bought an HP Linux computer with
two CPU AMD opteron, and I have installed Linux Red Hat 3.0
WS.

I have installed a calculation software that requires the
use of
parallel processing, so I need an mpi installation.
Our software has to use lam-7.1.1, and it brings some
instructions
to install it, but there is another lam version already
installed
in the computer ( 6.5.9 ) that prevents our software from
running ok.

Now I have the two lam versions running, and I think it is a
complete
chaos...
How should I do to remove all the lam installations, and
start from scratch?

Thanking you in advance for your attention and help, and
best regards,

Iņigo Aranguren

If the LAM 6.5.9 release came from an RPM (which it likely
was if it  
came with your Red Hat install), you would be best off to
uninstall  
the RPM.  This can be accomplished with with:

   rpm -evh lam

If this doesn't work, you might want to look through the
Red Hat  
documentation on removing RPM installed packages.

Hope this helps,

Brian
