Yes, was using CVS.  I followed the directions on the CVS website to get
the CVS checkout done.

But, it turns out there is another problem here which I probably need to
file as a bug.  I actually tracked this one down.  This error message is
produced when the output/target .tif file already exists.  It should
give an error message that the target/output file already exists.  When
I deleted the target/output file, all worked fine and produced a proper
output file.
