Just busy, that's all...

install(CODE) and install(SCRIPT) code is run at "make install" time. By
default, CPack does a "make install" to an intermediate location in the
build tree (underneath _CPack_Packages in your build tree) as part of
building the final installer.

I don't know about the CPack post script stuff, or the OS X version
differences you're talking about. I'll have to investigate / take a look
later, but not sure I'll have the time for it this week. If you can give me
easy-to-reproduce steps, that might help.


Hope this helps,
David
