I think i just found the answer...

currently installed version of Xcode, 11.5, is not supported by MacPorts. For your currently installed system, only the following versions of Xcode are supported: 11.4.1 11.4 11.3.1 11.3

[smashbang (Andrew Kececi)]

Close ticket resolved..

[kencu (Ken)]

probably a real error...see 60703

[jmroot (Joshua Root)]

clang-1100.0.33.8 corresponds to Xcode 11.1. Looks like your Command Line Tools are outdated?

Closing since the reporter said we should close the ticket and the command line tools were found to be outdated.
