Just ran a quick test adding the above to simplopal.

Thanks for that.  Its a little step closer.  I need to do more analysis
to see where I am at now.

I'm using 3.10.4, which is the default version supplied in the Debian
Wheezy release.  conopal is not available from the Debian repositories.

I have not (yet) tried building from src.  Is conopal in the

Appreciate the help, thank you.
