How about this? (untested)

if not (type.startswith('gecko') or kwargs['buildNum'].isdigit()):

+            if no_gecko_build and not kwargs['buildNum'].isdigit():
                 raise TypeError('Build number must be numerical')

             kwargs['releaseBuild'] = True
     if len(args) > 0:
         kwargs['outFile'] = args[0]
