 The actual relevant error message in the log is before this point,
 therefore, as always, please attach the main.log.

 /opt/local/lib/libJPEG.dylib?

 The libjpeg-turbo port (or the jpeg port, if you prefer) provides
 /opt/local/lib/libjpeg.dylib. No port provides
 /opt/local/lib/libJPEG.dylib. macOS provides
 /System/Library/Frameworks/ImageIO.framework/Versions/A/Resources/libJPEG.dylib
 and some things in the OS link with that. Apple's libJPEG.dylib and
 MacPorts' libjpeg.dylib are not the same and are not interchangeable. For
 one thing, Apple's has `__cg_jpeg_resync_to_restart` and MacPorts'
 doesn't.

 An error message about /opt/local/lib/libJPEG.dylib can only arise on
 systems with case-insensitive filesystems (whch is the default) and when
 the environment variable `DYLD_LIBRARY_PATH` has been set to
 /opt/local/lib. If you have that set in your environment, unset it. If it
 is the build system that is setting this, it must be changed not to do
 that. Let us wait and see what your main.log contains before we do further
 analysis.
