[vtkusers] Trouble building CVS on OS X 10.5

[Russel Howe]

I did a CVS checkout this morning and am attempting to build on OS X 
10.5.  There appears to be either a missing configuration variable or a 
missing header file as the build fails with

In file included from

I am using cmake version 2.6-patch 0 installed from Macports.

I have enabled Python wrapping, disabled Cocoa and enabled Carbon.

What am I missing?
