Comment (by dbevans):

 Replying to [comment:12 jmroot]:
 > It is, sort of. Since g-ir-scanner isn't using the CFLAGS (including
 `-isysroot${configure.sdkroot}`) that MacPorts gives to poppler's
 configure script, distutils defaults to using the sysroot that was
 configured when python was built.

 must be some way to make g-ir-scanner use the current sysroot.

 I agree that rebuilding everything isn't really needed but in this case
 given your analysis,  isn't rebuilding python with Xcode11 sufficient to
 cause gobject-introspection to use the right sysroot?
