===> Compilation failed unexpectedly.
Try to set MAKE_JOBS_UNSAFE=yes and rebuild before reporting the failure to
the maintainer.

make: stopped in /usr/ports/security/sssd

was reported before as http://www.freebsd.org/cgi/query-pr.cgi?pr=ports/187789 but closed instead reassigned to ports/krb5.

How-To-Repeat: cd /usr/ports
svn up
cd security/sssd
make clean build

or

cd /usr/ports
svn up
cd security/krb5
make clean build

In both cases port security/krb5 doesn't build and exausts various errors. Setting "MAKE_JOBS_UNSAFE=yes" does not lead to successfully building.
