wxWidgets-3.0 warnings with Big Sur

[Ken Cunningham]

Interesting.

/opt/local/Library/Frameworks/wxWidgets.framework/Versions/wxWidgets/3.0/lib/libwx_osx_cocoau_core-3.0.0.4.0.dylib
and
/opt/local/Library/Frameworks/wxWidgets.framework/Versions/wxWidgets/3.0/lib/libwx_osx_cocoau_core-3.0.dylib
are actually the same library; one is just a symlink to the other:

% ls -la /opt/local/Library/Frameworks/wxWidgets.framework/Versions/wxWidgets/3.0/lib/libwx_osx_cocoau_core-3.0*           
-rwxr-xr-x  1 macports  wheel  4563192 31 Oct  2019 /opt/local/Library/Frameworks/wxWidgets.framework/Versions/wxWidgets/3.0/lib/libwx_osx_cocoau_core-3.0.0.4.0.dylib
lrwxr-xr-x  1 root      wheel       37 31 Oct  2019 /opt/local/Library/Frameworks/wxWidgets.framework/Versions/wxWidgets/3.0/lib/libwx_osx_cocoau_core-3.0.0.dylib -> libwx_osx_cocoau_core-3.0.0.4.0.dylib
lrwxr-xr-x  1 root      wheel       33 31 Oct  2019 /opt/local/Library/Frameworks/wxWidgets.framework/Versions/wxWidgets/3.0/lib/libwx_osx_cocoau_core-3.0.dylib -> libwx_osx_cocoau_core-3.0.0.dylib

I have only one referenced:

% otool -L /opt/local/bin/gnuplot | grep core  
	/opt/local/Library/Frameworks/wxWidgets.framework/Versions/wxWidgets/3.0/lib/libwx_osx_cocoau_core-3.0.dylib (compatibility version 5.0.0, current version 5.0.0)

and I see no such warnings on Catalina, but perhaps this is related to the new way that dylibs are found on BigSur, and it’s getting confused by the symlink…

It’s very hard to imagine nobody would have ever noticed that before, though.
