Due to packaging problems on Apple's part, software that compiles
against APR requires the standalone Command Line Tools.
EOS
if MacOS.version >= :mavericks
message += <<-EOS.undent
Either
`brew install apr-util`
or
`xcode-select --install`
to install APR.
EOS
else
message += <<-EOS.undent
The standalone package can be obtained from
https://developer.apple.com/downloads/,
or it can be installed via Xcode's preferences.
Or you can `brew install apr-util`.
