First download SALOME-MECA-2008.1-GPL.tgz from the CAELinux website. Then starting as a normal user:

tar xvzf SALOME-MECA-2008.1-GPL.tgz
su
mv SALOME-MECA-2008.1-GPL/ /opt/
exit
cd /opt/SALOME-MECA-2008.1-GPL/postinstall/
./postinstall.py
su
chown -R root:root /opt/
exit
/opt/SALOME-MECA-2008.1-GPL/runSalomeMeca

If you are lucky everything will just work, however if you are like me and encounter an error when running runSalomeMeca that contains "Failed to narrow the root naming context" check your /etc/hosts file. Mine originally looked like:

# Do not remove the following line, or various programs
# that require network functionality will fail.
127.0.0.1 localhost.localdomain localhost localhost
::1 localhost6.localdomain6 localhost6

Where that second localhost should have been my hostname for example:

127.0.0.1 localhost.localdomain localhost lintop
