Homebrew is my favorite package manager. If you installed Xcode just for brew than this post might be interesting for you.

Kenneth Reitz created a GCC Installer for OSX without Xcode! Thank you. This package is about 500 MB. Compared to Xcode you save at least 1,5 GB on your SSD.

So let’s go to work:

• Remove Xcode

[code]sudo /Developer/Library/uninstall-devtools --mode=all[/code]
This will delete Xcode. For more details see John’s post

• Download and install GCC for Mac without Xcode

Currently 10.6 and 10.7 packages are available at https://github.com/kennethreitz/osx-gcc-installer/downloads

• Install brew

/usr/bin/ruby -e "$(curl -fsSL https://raw.github.com/gist/323731)"

• You’re done

You can verify your success when you receive meaningful version by calling gcc --version and brew --version

Caution:
You don’t need Xcode for formulas like gradle, groovy, maven, tomcat etc. Nevertheless some formulas will require Xcode!
