[MonoTouch] [Monotouch] MonoMac projects cannot compile: ibtool exited with code 1

[fmuaddib]

I'm moving my first steps in MonoMac.

But I stopped right at the beginning due to some configuration error.
I've created a new ManoMac project in MonoDevelop, and then tried some
other sample MonoMac xamarin projects from GitHub, but I always get
this error compiling:

Error: Can't run /Developer/usr/bin/ibtool (no such file).
ibtool exited with code 1

My configuration:

Operating System:
	Mac OS X 10.7.3
MonoDevelop 2.8.6.5
Runtime:
	Mono 2.10.8 (tarball Mon Dec 19 17:43:18 EST 2011)
	GTK 2.24.5
	GTK# (2.12.0.0)
Mono for Android not installed
Apple Developer Tools:
	 Xcode 4.3.1 (1176)
	 Build 4E1019
Monotouch: 5.2.5
MonoDevelop.MonoMac 2.6.0.0

All my Monotouch projects compile fine, and I have no problem with the
last XCode (following the Xamarin guidelines I successfully upgraded
XCode and moved it from the obsolete Developer folder to the
Application folder, and downloaded the updated developer command line
tools from apple).

I've tried reinstalling MonoDevelop, but with no success. I always
get: "Error: ibtool returned error code 1."

Any help is appreciated.
