Comment:

 InstallationCheck script added in r43954 (trunk) and r43956 (1.7 branch)
 and what will be needed in the MacPorts port (commented-out) in r43955.

 InstallationCheck works fine on 10.3-10.5, but does present the warning
 sheet about the package needing to run a script to check for requirements.
 10.4 packages introduce a distribution file which can be used to do the
 same thing, but these are more lengthy (usually use PackageMaker to
 generate them) and are in JavaScript.  Hence, for simplicity I went with
 the InstallationCheck script.
