Help getting started -- trying to build csound package

[Forrest Cahoon]

Hi, I'm brand new, having just signed up to help with the csound package.

The first thing I'm trying to do is to use the git-buildpackage tools
to clone the repository and do a build.  I'm getting the repository,
but the build fails rather quickly.  Can anyone help me understand
what's going on here?

Here's my terminal session:

Branch upstream set up to track remote branch upstream from origin.
Branch pristine-tar set up to track remote branch pristine-tar from origin.
