hmm.   USE_GNU_TOOLS+=     lex is actually supposed to do more than
make sure flex is installed.  It also should allow the pcb configure
script to find libfl.a (-lfl).  That _should_ have fixed it.  I'll try
to look more into this.

Right.  This is certainly the problem.  Its even a pcb FAQ....

I see that there is a -L/usr/pkg/lib up there.  So I guess the devel/flex 
buildlink3 stuff isn't set up right.  Otherwise we would find -lfl.

It is strange that -ll is not included, but I'm still wondering why
USE_GNU_TOOLS+=	lex
didn't help pcb find -lfl....

I'll look more tonight.
