[vtkusers] compiling vtk 5 with tcl on mac intel

[Donald Johnson]

I have been trying to compile vtk on a mac book with running MacOSX  
10.4.10, gcc v 4.01. If i just try to build then library and examples  
everything works correctly, however if i try to make the tcl bindings  
cmake gives the following error durring configuring and exits.

RegularExpression::compile(): Nested *?+.
RegularExpression::compile(): Error in compile.

The path "/Users/nalkar/Projects/C++/VTk/VTK 5.0.2/Utilities/TclTk/ 
resources/tk8.4" is valid so im not sure what is causing this or how  
to attempt to correct the error.
