Please note we will close your issue without comment if you delete, do not read or do not fill out the issue checklist below and provide ALL the requested information. If you repeatedly fail to use the issue template, we will block you from ever submitting issues to Homebrew again.

Please always follow these steps:

• Confirmed this is a problem with brew installing one, specific Homebrew/homebrew-core formula (not cask or tap) and not every time you run brew? If it's a general brew problem please file this issue at https://github.com/Homebrew/brew/issues/new. If it's a brew cask problem please file this issue at https://github.com/Homebrew/caskroom/homebrew-cask/new. If it's a tap (e.g. Homebrew/homebrew-php) problem please file this issue at the tap.
• Ran brew update and retried your prior step?
• Ran brew doctor, fixed all issues and retried your prior step?
• Ran brew gist-logs <formula> (where <formula> is the name of the formula that failed) and included the output link?

I already installed it from bottle.

• If brew gist-logs didn't work: ran brew config and brew doctor and included their output with your issue?

To help us debug your issue please explain:

• What you were trying to do (and why)
• What happened (include command output)
• What you expected to happen
• Step-by-step reproduction instructions (by running brew install commands)

Didn't notice

Warning: Xcode is installed to a directory with a space in the name.
This will cause some formulae to fail to build.

in brew doctor

[fxcoudert]

Yeah, my guess was right :)

[SConaway]

Is there a way to fix this? Patch the `makefile`?
