43. nwchem revisited. Install on new debian machine

Here's a streamlined version of compiling and setting up nwchem with mpich2 support on a virgin debian testing (wheezy) 64 bit computer. I'm working on a build guide for nwchem 6.1 -- currently it builds fine but all jobs end with a Segmentation Violation error and exits with status 11.

Start by running
sudo apt-get install build-essential  gfortran
Edit these two files (the preferences one will most likely not exist)
/etc/apt/sources.list

deb ftp://ftp.au.debian.org/debian/ testing main contrib non-free
deb ftp://ftp.au.debian.org/debian/ stable main contrib non-free
deb ftp://ftp.au.debian.org/debian/ unstable main contrib non-free

/etc/apt/preferences

 Package: *
Pin: release a=testing
Pin-Priority: 990

Package: *
Pin: release a=unstable
Pin-Priority: -10

Package: *
Pin: release a=stable
Pin-Priority: 10

IMPORTANT: the pin-priority for stable must be positive (here +10), or it won't work.

Run
sudo apt-get install mpich2=1.2.1.1-5 libmpich2-dev=1.2.1.1-5

Set the Pin-priority to -10 for stable again.

sudo su
echo "mpich2 hold"|dpkg --set-selections
echo "libmpich2-dev hold"|dpkg --set-selections
mkdir ~/nwchem
cd ~/nwchem
touch buildconf.sh
chmod +x buildconf.sh

(EDIT 21/02/2012: I accidentally put a bad csh-formatted buildconf.sh file at the beginning. Then I put an incomplete bash version. It should work now.)

In buildconf.sh put
export LARGE_FILES=TRUE
export TCGRSH=/usr/local/bin/ssh
export NWCHEM_TOP=/home/myhome/nwchem/nwchem-6.0
export NWCHEM_TARGET=LINUX64
export NWCHEM_MODULES=all
export USE_MPI=y
export USE_MPIF=y
export MPI_LOC=/usr
export MPI_INCLUDE=$MPI_LOC/include/mpich2

cd $NWCHEM_TOP/src
make clean
make nwchem_config
make FC=gfortran

Then download the source code for nwchem

wget http://www.nwchem-sw.org/images/Nwchem-6.0.tar.gz
tar -xvf Nwchem-6.0.tar.gz

To start building:
./buildconf.sh

Once it's built:
echo "PATH=$PATH:/home/myname/nwchem/nwchem-6.0/bin/LINUX64" >> ~/.bashrc
source ~/.bashrc

Prepare mpd
echo "MPD_SECRETWORD=jibberjabber" >> ~/.mpd.conf
chmod 600 ~/.mpd.conf
mpd --ncpus=3 &

Prepare for a test-run
touch nwchem.nw
Put the following in the nwchem.nw file:

start benzene

end
basis
 H library sto-3g
 c library sto-3g
end
dft
    xc b3lyp
end
task dft optimize

Launch the job:
mpdrun -n 2 nwchem nwchem.nw

And you should be ready to go


Edit: 12/02/2012 It looks like version of nwchem currently in SID is built with mpi support: http://packages.debian.org/sid/nwchem . I haven't checked it out.
