Comment (by pftbest):

 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 1) port upgrade outdated - ffmpeg build fails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 6) port upgrade outdated - ok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.
