I've just updated my Xcode installation on Lion to 4.3, and now I cannot
install the latest build of Phonegap 1.4.1: the installer says I do not have
the iOS SDK installed. Xcode 4.3 makes
significant changes in the layout of the SDK's, etc. on OS X: it's a single
standalone app that is installed in /Applications. /Developer is no longer
used. I suspect that this confusing the installer. Most likely a re-architected installer to support the new developer configuration in Xcode 4.3 is required. Obviously this is a showstopper because I cannot develop a PhoneGap application if PhoneGap cannot be installed.
