The apparent first error.

I have the same issue -- Big Sur 11.4, port 2.7.1

[reneeotten (Renee Otten)]

perhaps updating to the latest version (10.2) would help to resolve these issues

[neilt (Neil Tiffin)]

I can confirm that changing the following lines in the Portfiles allows it to compile to apparent completion and installs. Had a lot of non-fatal errors, but it did not stop the compile or install. This is at least better that what exists as of 16 June 2021.
