[Cbc] Compiling and installing CBC in Mac OS X (10.8.2)

I was able to replicate this problem. It is not specific to OSX or that
particular release. It also happens in trunk on Linux. I will try to
investigate. If you have an account already on TRAC, a bug report would be
helpful to keep track of this. If not, the registration mechanism is broken
at the moment, so this e-mail will have to suffice.

Cheers,

Ted
