The problem with this is that namcap does not know anything about 
$srcdir (and how can it) so cannot check for references to it.  This is 
unlike the check for missing backup files that is already in 
check_package() which should probably be in namcap...

I also tested this in large packages (e.g. openoffice) and on my system 
(2GHz) it takes ~10sec which is a very small fraction of the build time.

As an aside, extracting and grepping through the entire core+extra+some 
of community takes me ~10min.  Per package this is a tiny amount of time 
and includes extraction of tarball and not having files in the cache.
