OpenMPI Slackbuild Script for Slamd64 12.1

I've just got OpenMPI to work on my Slamd64 12.1 system. I really hate cluttering the system. Therefore, I just build the package to ease removing it when I want to upgrade to a newer OpenMPI version later. This is the slackbuild script:

#!/bin/sh

# Slackware build script for Open MPI

PRGNAM=openmpi
VERSION=${VERSION:-1.3.3}
ARCH=${ARCH:-x86_64}
BUILD=${BUILD:-1}
TAG=${TAG:-_SBo}

CWD=$(pwd)
TMP=${TMP:-/tmp/SBo}
PKG=$TMP/package-$PRGNAM
OUTPUT=${OUTPUT:-/tmp}

if [ "$ARCH" = "i486" ]; then
  SLKCFLAGS="-O2 -march=i486 -mtune=i686"
elif [ "$ARCH" = "i686" ]; then
  SLKCFLAGS="-O2 -march=i686 -mtune=i686"
elif [ "$ARCH" = "x86_64" ]; then
  SLKCFLAGS="-O2 -fPIC"
fi

set -e

rm -rf $PKG
mkdir -p $TMP $PKG $OUTPUT
cd $TMP
rm -rf $PRGNAM-$VERSION
tar xvf $CWD/$PRGNAM-$VERSION.tar.bz2
cd $PRGNAM-$VERSION
chown -R root:root .

mkdir -p $PKG/install
cat $CWD/slack-desc > $PKG/install/slack-desc

cd $PKG
/sbin/makepkg -l y -c n $OUTPUT/$PRGNAM-$VERSION-$ARCH-$BUILD$TAG.tgz

That's it. Now, I can upgrade the package easily later. Anyway, I used OpenMPI 1.3.3 for my current experimental side projects.
