gexiv2 2-0.12.1_0 Failed to build gexiv2: command execution failed

[thebitmaster]

I upgraded to Catalina and XTools and did a full uninstall then re-install of Macports 2.6.3. xcode-select version 2373 Catalina 10.15.7 (19H2)

I'm trying to build the gimp but am getting a failure on gexiv2. I've done the various cleanings suggested and it still happens. Additional searches for similar problems haven't helped.

I'm an experienced tester but this is my first Github TRAC submission so further input on improving my bug reports is welcome.

From the main.log file, which I am also attaching.
