We still have the problem that any time a package update is done it
might pull in a newer Perl, which will change the path, but our
Jenkins slave never picks it up until the VM is rebooted.

I wonder if we can solve this by instead of putting all these
env vars in the main bash profile, we create a

   'jenkins-ci.sh'

that contains all the env variables. We can then source that
from the bash profile, and also source it as the first thing
we do in every build job too. 


Regards,
Daniel
