autogen.sh should have taken care of that for you.  If not, then let me 
know and I'll fix it.

I don't know how nailed down the interface is, but gerbv was just split 
apart into libgerbv which contains things like the rs274-x and drill 
file parsers and then the actual application.  Don't know if that would 
be useful to you in your work.  You might ask on the gerbv developers 
list.  It is a low traffic list and at least one of the key gerbv 
developers I think doesn't read this one.

I think at one time there was some interest in making the output of 
gerbv be a more common subset of rs274-x so this would be good to 
feedback to the gerbv developers list too.
