I think I'll increase the noise level on the list a little, since this
invloves more than a couple people.

Okay, I see the reference to the directory:

    overflow_toolbox_dir = os.path.join(overflow_prefix, "toolbox")

But, there is no directory named "toolbox" in Overflow, at least not any
more.  There is this directory:

   1 drwxrwxr-x    5 root     root         1024 Nov 20 18:28 tools/

Perhaps Jean-Marc changed the name?

Also, I set the overflow_prefix to


and NOT to


because the include directory is under the vflow directory.  Yo, what up wit
dat?  Is that what it should be set to?  Or should I have "installed" Overflow
into my system directories?

In short, compiling Piper worked fine, but I can't run it now 8-(  It seems
like a quick fix though, however I'd like to get a concensus.
