How to include new dirs in @INC

[Paul Schmehl]

Somehow I missed Anton's response, so I'm copying it here so I can respond 
as well.

I can certainly do that, by patching the scripts.

Probably a bad choice for a port.  :-)

Here's the hierarchy:

And yes, the two subdirs contained identically named modules but they are 
different.  (IOW, the code is not identical.)

After checking the scripts, all of them refer to Bro::Module except one. 
So I can put that one module (IP4.pm) in /mach and solve the problem that 
way.  The others appear to be correctly coded.
