Mac Ports Error Starting GIMP 2.10.20

[bruceagarrett]

As there is no MacOS installed for the current stable version, I thought I'd try Macports as suggested on the downloads page. Everything looked good as the pieces were fetched and then configured, built and installed. But GIMP will not run. Instead I get the following:

Bagheera:MacOS bruce$ ./GIMP
2020-11-24 12:21:50.235 GIMP[61273:512327] Failed to connect (cancelButton) outlet from (ScriptExecController) to (NSButton): missing setter or instance variable
2020-11-24 12:21:50.235 GIMP[61273:512327] Failed to connect (messageTextField) outlet from (ScriptExecController) to (NSTextField): missing setter or instance variable
Cannot open display:


Please advise if this is something I can fix, or if this shows a bug I should report. 

FYI...I am running MacOS 10.13.6 and XCode 10.1. Mac Ports version is 2.6.4. Here is what my system profiler reports:
