XCode 4.3 does not install the Unix development environment by default anymore. Go to the XCode preferences, and then to the Download pane, there should be an Install button for that.<div><br></div><div><br></div><div>Aristid</div>

Hello - I&#39;m a new user, having some trouble installing the Haskell Platform (2011.4.0.0 64bit.pkg) on a Macbook Pro (10.7.3).  I installed Xcode 4.3.1 (4E1019), then the Haskell Platform. When I double-click on the Platform package icon, I get an installation dialogue with an error message reading &quot;Developer Tools Missing - Please install Xcode developer tools first.&quot;  Are Xcode developer tools something distinct from Xcode itself?  I&#39;m mystified by this error message.  Any assistance would be greatly appreciated - thank you.
