ffmpeg 4.2_0+gpl2+gpl3+nonfree fails to build if libbluray is not installed

[pftbest (Vadzim Dambrouski)]

Manually installing libbluray fixed the issue.

Full log is in attachment.

It is already a dependency, so it should be installed.

Maybe it was deactivated for some reason, and using port install libbluray reactivated it?

Searching for dependency: libbluray
Found Dependency: receipt exists for libbluray

indicates that libbluray appeared to be installed and active. Seeing the config.log would be necessary to see how exactly it failed to find it with pkgconfig.

Sorry, I forgot to save config.log.

I failed to mention that I also had a small problem with libxml2 on this upgrade. I had created include/libxml2/unicode symlink some time ago for development reasons, but now the latest version of libxml2 provides this symlink too, so there was a conflict on upgrade. Which I solved by removing old symlink.

The whole interaction went like this:

1) port upgrade outdated - ffmpeg build fails
2) port install libbluray - error message about libxml2
3) removed symlink
4) port activate libxml2 - ok
5) port install libbluray - ok
6) port upgrade outdated - ok

Initially I thought I was just missing libbluray and it was not related, but now I think this might be the root cause of the issue.

Feel free to close this ticket, it was probably a misconfiguration on my side.
