Trying to Install Io language on Mac (Catalina: 10.15.7 (19H1824)), using MacPorts (2.7.2).

Failed to build:

Error: Processing of port Io failed

Performed port clean Io, tried again: no success. Re-installed current version of Command-Line-Tools & deleted the com.apple.....in-progress file: no success.

Couldn't find anything searching terms "Io build", "iocairo", and others; and searching advanced for "port [is] 'Io'".

Relevant message from log file (/opt/local/var/macports/logs/_opt_local_var_macports_sources_rsync.macports.org_release_tarballs_ports_lang_Io/Io/main.log):
