I created a .pkg file of my Mac app using XCode 4. I installed it using the terminal successfully, however when I double click on the .pkg file, I get a message that says, "... can't be installed on this computer".

Any suggestions?

Thanks. 

**EDIT:** This is the error message that I get. I created package by going to **Product->Archive**. Then in the Organizer I clicked **Share->Mac OSX App Store Package(.pkg)** and then save the package to the desktop.

This is what's inside the package.

Furthermore, I've inspected the build settings between XCode 3 and 4 is the following
