It tries to autodetect, but then fails in a later step:

This is explained in libgphoto2_port/config.log:

There seems to be some GNU/kFreeBSD portability issue in libusb.h - the
same issue that causes a build failure in libghoto2 later.
The attached patch may help with this. (I applied it directly to my
system libusb.h). After this I got a successful build on kfreebsd-amd64
