Hi, I'm running MP 2.5.4 on a 2010 MBP with the latest version of Sierra (10.12.6/Darwin16.7.0).

As mentioned in ticket #58072, I recently completed a selfupdate after not doing so for a long while. When I tried to run port upgrade outdated and/or port rev-upgrade, something failed and I was presented with a list of broken ports, e.g.:

--->  Found 42 broken files, matching files to ports
rb-eventmachine is using libstdc++ (this installation is configured to use libc++)
sqlmap is using libstdc++ (this installation is configured to use libc++)
openmpi-gcc5 is using libstdc++ (this installation is configured to use libc++)
openmpi-gcc6 is using libstdc++ (this installation is configured to use libc++)
openmpi-gcc49 is using libstdc++ (this installation is configured to use libc++)
--->  Found 11 broken ports, determining rebuild order

You can always run 'port rev-upgrade' again to fix errors.
The following ports will be rebuilt:
 R-app @1.68
 openmpi-gcc6 @3.0.0+fortran
 openmpi-gcc49 @3.0.0+fortran
 enblend @4.1.5
 ntop @5.0.1
 objectmarker @20070501
 libkdcraw @4.14.3
 libVLC @2.2.8+quartz
 rb-eventmachine @0.12.10
 sqlmap @0.9+python27
 openmpi-gcc5 @3.0.0+fortran
Continue? [Y/n]:

Initially, the list was much longer and I was able to manually upgrade some of the ports (not shown). The first one I came here for help with is the ticket mentioned above (​#58072). I was redirected to try the solution suggested at ​ticket #58066 by kencu, which worked.

When I tried to manually upgrade the port objectmarker, it failed and I noticed that some of the broken files are tied to opencv. I tried a similar solution with opencv using the one described in #58066 by trying port -v -d install openCV +avx2 +contrib +debug +eigen +gdal +opencl +openni +python27 +qt5 +tbb +vtk. This did not work.

openCV is critical to the work I do. Help with this is very much appreciated.

The log file for opencv is attached.

Looks like the error in the log is:

Or, more legibly:

"This file was generated by an older version of protoc which is incompatible with your Protocol Buffer headers. Please regenerate this file with a newer version of protoc."

Which is already filed as #56349.
