In the future, please use WikiFormatting, fill in the Port field and Cc the port maintainers (port info --maintainers harfbuzz-icu).

From your output:

Incompatible library version: /opt/local/lib/libharfbuzz-icu.0.dylib requires version 929.0.0 or later, but /opt/local/lib/libharfbuzz.0.dylib provides version 926.0.0
DEBUG: Marking /opt/local/lib/libharfbuzz-icu.0.dylib as broken

You need to upgrade harfbuzz first. On my computer:

$ otool -L /opt/local/lib/libharfbuzz.0.dylib
/opt/local/lib/libharfbuzz.0.dylib:
	/opt/local/lib/libharfbuzz.0.dylib (compatibility version 929.0.0, current version 929.0.0)

harfbuzz is a dependency of harfbuzz-icu, so MacPorts should have upgraded harfbuzz before upgrading harfbuzz-icu. However, if harfbuzz-icu was upgraded due to rev-upgrade, then that would not necessarily have happened, because of a bug, which will be fixed in MacPorts 2.3.0.
