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)
