#57692: cargo upgrade to 0.31.1_1 fails due to dyld: Symbol not found

Xcode 10.1 on macOS 10.14.1

cargo upgrade to 0.31.1_1 fails:
{{{
$ sudo port -sv upgrade cargo
...
dyld: Symbol not found: __cg_jpeg_resync_to_restart
Referenced from:
/System/Library/Frameworks/ImageIO.framework/Versions/A/ImageIO
Expected in: /opt/local/lib/libJPEG.dylib
...
}}}
I believe that this issue is due to the wrong libJPEG.dylib is loaded,
i.e.
{{{
/opt/local/lib/libJPEG.dylib
}}}
is loaded instead of the correct:
{{{
/System/Library/Frameworks/ImageIO.framework/Versions/A/Resources/libJPEG.dylib
}}}
This issue has been encountered in the past on other ports, for example:
#57594.
