==> Dissecting the script, it looks liek it is trying to install a file: agrep-2.04_1.darwin_20.x86_64.tbz2 which does not exist in any of the follwoing repositories:

​https://packages.macports.org/agrep
​http://mirror.fcix.net/macports/packages/agrep
​https://ywg.ca.packages.macports.org/mirror/macports/packages/agrep

==> Have searched the internet for the file: agrep-2.04_1.darwin_20.x86_64.tbz2 but nothing exists.

==> Please advise on how we can install agrep

Add the main.log file mentioned in the error message to this ticket.

It fails with Xcode 12 or later due to implicit function declarations. The developers have been advised what they need to do to fix it and have not reacted:

If you or anyone would like to submit fixes for these issues to the developers I'm sure they would appreciate it.
