Dear Peter,
I recently had a similar problem with the same Haskell Platform version
but on a Macmini (running Lion as well).
I learnt that you have to install the 'command line tools' by using the
'preferences' of your XCode installation. After that, everything will work.
Best regards,
Salvador.

Hello - I'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 "Developer Tools Missing -
Please install Xcode developer tools first." Are Xcode developer
tools something distinct from Xcode itself? I'm mystified by this
error message. Any assistance would be greatly appreciated - thank you.
