Hi Radu,
I know what mercurial is and have used it in the past.  I was just confused
as to why it issued the error at the beginning of my make.

I am running a pentium 4 2.6ghz running ubuntu 10.10.  What version
information would be useful?

I am downloading diamondback as I type this.  Hopefully that will work!

Thanks much
Brian
