Mavericks, corebluetooth, BBC IPlayer

[moonson.co]

A recent update of BBC IPlayer (2.5.5, not the fairly recent big update) is refusing to run on my 2009 mac mini on 10.9.5 Mavericks.
If the error message is any help, the first and possibly main thing it's complaining about is the lack of /System/Library/Frameworks/CoreBluetooth.framework/Versions/A/CoreBluetooth - which Apple developers site says wasn't included until 10.10
But i can't find a CoreBluetooth.framework to download, and anyway would it have any value in 10.9.5? Might it just persuade the app. that it's there, so it can move on?
FWIW i'm not using IPlayer with anything Bluetooth, not am I intending to
BBC tech support no help
(I'd even be happy to find a download of the previous version of IPlayer downloads, that worked perfectly well)

for what it's worth (if anyone finds this on a search), clearly a few people were having this problem and after a week there's now another update [2.5.6] that doesn't have that problem...
