[Mono-osx] 999+ errors when incudling Mono Framework in XCode Project

[Dave]

Mac OS X 10.10.4 - Yosemite.
XCode 6.3.1

Hi,

I added the Mono Framework my XCode project and tried to compile, but I get 999+ Errors for instance:


/Library/Frameworks/Mono.framework/Versions/Current/include/llvm/CodeGen/PBQP/math.h:13:10: 'algorithm' file not found

/Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX10.10.sdk/System/Library/Frameworks/CoreFoundation.framework/Headers/CoreFoundation.h:11:10: Could not build module ‘Darwin'

Not sure why this should be? 

I installed Mono using MonoFramework-MDK-4.0.2.5.macos10.xamarin.x86.pk 

Any one have any ideas?

Cheers
Dave
