Comment (by kencu):

 That is called an ODR violation, and it is the primary concern with this
 process, for sure.

 But -- we cannot hope to force all of MacPorts to use a new libc++.dylib,
 and even if we did, the issue generally arises when working against system
 software built against /usr/lib/libc++.dylib anyway.

 So -- that is exactly what we are waiting to see if it will become an
 issue, as all the conversation above was about [ticket:62426#comment:5].

 We shall see :>
