I'm sure the SDK is installed (I've reinstalled XCode and the command line tools, and I can compile my own projects and most other ports), but it may be a newer version? XCode is version 12.4.

The logfile (attached) shows a number of missing X-symbols during linking (_XChangeProperty, _XCloseDisplay,...).

Log of the build attempt

Ignore the SDK error message. Start paying attention to it again after MacPorts 2.7.0 is released.

From the log, this looks like ​the well-known libtool macOS 11+ bug with undefined symbols, needing the usual fix (copied from the patch in the libtool port).

Looks like updating to 3.6.1 fixed this.
