Comment:

 > {{{

 '/Library/Developer/CommandLineTools/SDKs/MacOSX11.1.sdk' [-Wmissing-
 sysroot]

 This was because of an SDK path selection bug (#61866) in MacPorts 2.6.4
 on macOS 11 and later which was fixed in MacPorts 2.7.0.

 The original problem with undefined symbols should be fixed in the way
 [comment:3 originally indicated]. Only one of the configure script or the
 m4 files should be patched depending on whether or not the port uses
 autoreconf.

 PSA: Everyone please remember to use WikiFormatting and TracLinks when
 writing in Trac to keep things legible.
