Hello, I'm getting a build failure on x11-toolkits/qt5-gui and I'm sure it is because of configuration options ... somewhere, but I'm having trouble tracking it down.

1 - build failure

2 - where is that file?

[dvl@ava-pkg-02prd:/usr/local/poudriere/ports/clean/x11-toolkits/qt5-gui] $ grep application_p.h *
grep: files: Is a directory

I solved it with these instructions:
https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=247994#c3

I also remove "OPTIONS_UNSET+=X11" from my /etc/make.conf

OPTIONS_UNSET+=X11 was added by a previous admin. I'm hesitant to remove it, but that was the cause. I just had to track down which port really needed that to be on.
