Can you post the build errors please, as this is new.. it would be good
to fix it properly. Most likely, you need to "apt-get install intltool",
but without error output, I'm guessing.

I take it your checkout correctly added a "data" directory, and its not
thay you just need to cvs up -d ?

CVS is a big improvement over the last snapshot. I may have something
which could help redrawing speed, but the hellboard loading case...
probably not.
