Comment (by ryandesign):

 You did not attach a main.log file so we are missing some information that
 we like to have, such as your macOS version, architecture, port version,
 etc.

 Replying to [ticket:72310 barracuda156]:
 > Perhaps it fails to find MacPorts-provided `doxygen`?

 The portion of the log you shared clearly shows that it is running
 MacPorts `doxygen` at `/opt/local/bin/doxygen`:

 This is just a warning so I do not suspect that it is the cause of the
 build failure.

 `dot` is part of graphviz and is located at `${prefix}/bin/dot` so the
 path it is using is erroneous. I don't know whether this wrong path is in
 osmocore or doxygen.

 These might be the actual errors to correct. Or the real error might be
 somewhere else in your main.log file.
