Thanks, this works great.

OK, I'll work on this.

I think I have things working nicely. Here is the general order of
things done, 
   - configure CGDB then readline
   - compile readline, compile CGDB
     CGDB use's headers from $top_srcdir/readline-5.0 and libraries from
     $top_builddir/readline-5.0
   - install readline/CGDB

I was wondering if this is OK?

Finally, is there a way to not have readline install anything? Since I
linked statically to it, I don't need anything else from it.

Thanks,
