Thomas -
Thanks for reporting this issue, I've submitted a PR that should
address the issue. You can grab a freebsd version of the install
here:
https://ci1.netdef.org/browse/FRR-FRRPULLREQ-158/artifact/shared/FreeBSD-10-x86_64-Package/frr-test-20170130.002417.txz
Hopefully this will get integrated into master in the next day or so.
