freebsd stable - Jan 2017 - problems with KiCad (pcbnew) on 11-stable with boost-libs

Hi all,

in the last days I've updated my PC from 10.3-stable to 11.0-stable
and recompiled almost all installed ports.

I have had kicad-devel installed and now I have problems to get that
port working again. I've bootstrapped the kicad-devel port (look at the
Makefile) and build the last git version. The problem is, that the
pcb-editor pcbnew ist segfaulting at startup.

/libexec/ld-elf.so.1.debug...done.

I can reproduce it on a 2nd test machine that's newly installed.
Some investigations had the result that the system wide boost-libs in
the version 1.63 are the problem. I've checked out an old 1.55 version
and pcbnew ist running on one machine without segfaulting.

Michal (mr at freebsd.org) the port-maintainer informed me that the problem is
already known with Windows on amd64:
http://kicad-pcb.org/help/known-system-related-issues/
Suggeest there is installing the old boost-libs (1.56) which would'nt
work that easy on FreeBSD.


I don't have the skills to fix this for me and so my question here is
how I can temporarly fix that w/o clobbering the entire system with the
old boost_libs?

Is someone here using Kicad too?

regards,

Holm
