[vtkusers] OSX 10.6 TCL issue "libvtkRendering.5.4.dylib: GC capability mismatch" ( solution too )

[Bradley Lowekamp]

THANK YOU!

You recent fixes seems to be working for me! And I got 64-bit vtk tcl! Awesome, I hated running out of memory.

But...

I still had to add the -fobjc-gc flag for what ever reason. I build it for "i386;x86_64" with dynamic libraries. I take it you don't need to build it with that objc flag? I wonder what's odd about my system where it needed.

As the documentation indicates it just add support to the library for this feature, I am not sure there would be a down side to adding it.
