Logfile

It looks like you're running go version 1.17.13: ​https://trac.macports.org/attachment/ticket/66003/main.log#L85

The ​net/netip package requires go version 1.18 or higher.

Can you try upgrading go by running sudo port upgrade go and then see if wireguard-go builds and installs successfully?

[ryandesign (Ryan Carsten Schmidt)]

The go port is programmed to use go 1.17 on older versions of macOS, such as the one the user is using.

​https://github.com/macports/macports-ports/blob/master/lang/go/Portfile#L18-L25

Tons of go ports fail to build every day on the older OS versions on the buildbot because of this. Would be great to fix it, for example by upgrading go to a newer version on older systems, but the comment in the go port says that's not possible, but it doesn't say why.
