Comment (by fhgwright):

 Replying to [comment:4 ryandesign]:
 > The build procedure of what? If you mean you are setting the `SDKROOT`
 environment variable in your shell and MacPorts is not passing it through
 to the builds, that's intentional; most environment variables are
 deliberately not passed through. You can override `configure.sdk_version`
 or `configure.sdkroot` on the command line if you want to test a different
 SDK, e.g. `sudo port configure configure.sdk_version=11` (this assumes you
 have the macOS 11 SDK in the standard location) or `sudo port configure
 configure.sdkroot=/path/to/MacOSX11.sdk` (for an SDK located anywhre).

 No, I mean the ''project's'' build procedure.  Testing it as a port would
 add unnecessary friction.

 An example of why `legacy-support` should have its own ticket component,
 since this isn't a `ports` issue. :-)
