FYI:  PKG_CONFIG_PATH is the path to the pkg-config binary.

All you should need after the libecap "make install" is:
 ./configure --prefix=/usr --enable-ecap

There is a bug. The libecap library headers do not support C++11
compilers properly.

The libecap authors referred me to the patch found at
<https://github.com/freebsd/freebsd-ports/blob/master/www/libecap/files/patch-src__libecap__common__area.h>
when I encountered this earlier. They are already working on a better
fix that will be in a future release of libecap.
