../configure-ac --with-mpi=lam CPPFLAGS="-I/usr/local/lam/include/ -I(your TCL include-folder)" LDFLAGS= "-L/usr/local/lam/lib -L(your TCL lib-folder)" LD_LIBRARY_PATH="/usr/local/lam/lib:(your TCL lib-folder)"
Set the (your TCL include-folder) and (your TCL lib-folder) according to where your TCL is installed, with the form analogous to how the lam folder was declared in each flag. You can make a trial with OpenMPI also, but it is safer to install one MPI program at a time.

Thanks Aang and Olaf,
I uninstalled openmpi and reinstalled lam 7.1.4. I still have the problem
and it looks like you were right Aang. The error looks like this:
....
../ghosts.h:76:17:
error: mpi.h: No such file or directory
In file included from ../cells.h:54,
from ../thermostat.h:24,
from ../energy.h:17,
from ../initialize.c:24:
../ghosts.h:138: error: expected specifier-qualifier-list before ?MPI_Comm?
In file included from ../pressure.h:90,
from ../thermostat.h:25,
from ../energy.h:17,
from ../initialize.c:24:
...
I attached config.log's of both Espresso(from the obj-Core-pc-linux
directory) and Lam installation. I was not sure which of the config.log's
from the lam directory to send because there were a lot of them in different
folders. So I sent
you the one that was in the top directory( i.e. directly
in lam ). Let me know if I sent the right things :)
Hope you can figure out the error,
It's my first week reading about parallel computing so I'm very new to this
:)
Thanks,
