No, but

/opt/local/lib/libicui18n.72.dylib

does. Also,

rtemio at mbp-13 ~ % otool -L /opt/local/lib/libxml2.2.dylib                              
/opt/local/lib/libxml2.2.dylib:
	/opt/local/lib/libxml2.2.dylib (compatibility version 13.0.0, current version 13.3.0)
	/opt/local/lib/libz.1.dylib (compatibility version 1.0.0, current version 1.2.13)
	/opt/local/lib/liblzma.5.dylib (compatibility version 8.0.0, current version 8.7.0)
	/usr/lib/libSystem.B.dylib (compatibility version 1.0.0, current version 1319.0.0)
	/opt/local/lib/libiconv.2.dylib (compatibility version 9.0.0, current version 9.1.0)
	/opt/local/lib/libicui18n.71.dylib (compatibility version 71.0.0, current version 71.1.0)
	/opt/local/lib/libicuuc.71.dylib (compatibility version 71.0.0, current version 71.1.0)
	/opt/local/lib/libicudata.71.dylib (compatibility version 71.0.0, current version 71.1.0)

However, I am embarrassed to say that the problem with the compiler seems to have been cause by not updating the path to Xcode after replacing the RC2 by the final version. Indeed, after executing

sudo xcode-select --switch /Applications/Xcode.app/Contents/Developer 

And doing a port update clang seems to be working again! (The Emacs.app problem still persists, though).

Sorry for the snafu,

Artemio
