Macs allow a special type of dynamic linking at compile time called "weak
import" that means when the executable is loaded, the loader will not
require that library to be present.  It is up to your application then to
verify that the given library facilities are available before calling any of
them.  The purpose of this is to allow applications to optionally use system
libraries that may not be present on every system.

The warning message implies that Csound was attempting to do a weak link
against the Carbon framework but that it could not; apparently because you
are targetting 10.1 with the compiler.  If you have 10.2 or later installed,
then I suggest that you change the deployment target to 10.2.  It seems
likely that this could fix a lot of the issues you are experiencing.

This is an issue I have mentioned before.  Anyone packaging Csound on OS X
10.3 or 10.4 should set their deployment target to 10.2 (or 10.1 if they can
get it to work, but I believe CoreAudio is incomplete on 10.1).  If you do
not, then I believe no one on an earlier system will be able to use the
distribution.
