port rev-upgrade stumbles over -weak_framework library dependencies

[RJVB (René Bertin)]

While trying to get QtWebEngine (QWE) 5.7.0 to build on OS X 10.9 I ran into an issue with port rev-upgrade:

the QtWebEngineCore.framework links to the Bluetooth framework, called IOBluetooth on OS X 10.9, which contains the CoreBluetooth framework. QWE 5.7 now requires to 10.10 SDK to build, and that SDK provides the CoreBluetooth framework directly in /System/Library/Frameworks.

As a result, the QtWebEngineCore framework has a dependency on /System/Library/Frameworks/CoreBluetooth/.../CoreBluetooth, which evidently doesn't exist on 10.9 . The build system handles that by linking the framework with -weak_framework, and the resulting QtWebEngineCore framework loads just fine.

However, port rev-upgrade apparently only sees the dependency and not its weak nature, so an error is raised that shouldn't occur.

And what error is that?

The usual error about a missing library, in this case /System/Library/Frameworks/CoreBluetooth.framework/Versions/A/CoreBluetooth
