--------------------------------------+-------------------------------------
 The logic of the section handling darwin > 10 in the ld64 Portfile is
 flawed. By copying the ld and rebase files from /usr/bin into
 /opt/local/bin, MacPorts is locking the user into a snapshot of the Xcode
 currently installed when the ld64 package is built. The ld64 package
 should be creating symlinks to these files instead of copying them.
