Previously, the port would not build complaining about no autogen. With this patch, the port builds and installs.
I have no idea what I'm doing, this is my first time trying to build_depends, so please exercise extreme caution.
This gets me a little further than I was getting on https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=282185
Probably unrelated, when I did this, the port built, but then my system (current built yesterday) hung completely unresponsive...
