Comment:

 Slightly off-topic, but related to the pending patches posted here. Marcus
 requested the following three patches:

 Reasons as described by Marcus:
 * When building `.bundle files`, `build_arch` is not respected, and they
 are not universal
 * On older systems, `macosx_deployment_target` is not respected (10.3 is
 always used).

 My response:
 * I would be grateful for explanation how to test the first point.
 * If we are patching `MACOSX_DEPLOYMENT_TARGET`, shouldn't we at least do
 that consistently for all OS version?
 * I don't understand why `variant universal {}` is needed. Is this a bug
 in MacPorts base or where exactly lies the difference?
 * Do any of those patches address #52290?
