[MonoDevelop] Framework "Mono for iPhone" not Installed.

[Rick Checketts]

Hi

This is getting frustrating now MonoDevelop runs OK I write a simple  
Hello World app it compiles ok but with the following error:

Framework "Mono for iPhone" not Installed.

I have followed the installation instructions that were emailed to me  
after purchase and yet I am now getting this error.

Any help gratefully received.

Thanks

Rick
