Error when 'rake' command executed

[saltwat5r]

I'm getting the following errors when trying to 'rake', and so I can't compile Your library. Do you have any idea?

1 warning generated.

I ran into this and it seemed to be using some old version of ranlib and ar. I did this to point to newer versions: $ sudo mv /opt/local/bin/ranlib /opt/local/bin/ranlib.old $ sudo ln -s /Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/bin/ranlib /opt/local/bin/ranlib

sudo mv /opt/local/bin/ar /opt/local/bin/ar.old sudo ln -s /Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/bin/ar
