Minimal Xcode installation without iOS SDK

Question

I am in the progress of switching my MBP to run off an SSD, so I’ve been looking of ways to save harddisk space. Xcode with the iOS SDK weighs around 10GB, and since I don’t really use the iOS SDK for anything this seems like a good opportunity to save space.

Problem is that Apple seems to have removed all Xcode downloads that do not include the SDK. I have tried looking around the site and link-hacking, but nowwhere have I been able to find a minimal Xcode.

I don’t really care if it's Xcode4 or not, I just need it for Homebrew to work. Is it possible to find this somewhere?

(If not, is it safe to simply delete /Developer/Platforms/iPhoneSimulator.platform and /Developer/Platforms/iPhoneOS.platform)?
