• Alternatively (if the goal is to compile from the latest sources available), pull directly from development git repository, install couple of additional packages and run ./autogen.sh.

$ git clone git://git.geda-project.org/pcb.git pcb-git
$ sudo pkg install developer/build/automake-111 developer/build/autoconf developer/parser/bison
$ cd pcb-git
$ ./autogen.sh

• patch src/main.c. Add missing locale.h header file, as setlocale(3C) is consumed. Fixed by Dan McMahill in chset 8cbc19e5aa9572196f27d4e64db8337d80945803.
