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

[David Gobbi]

Hi Brad,

It's great to hear that it's working for you.  I've never used the
-fobjc-gc flag, and I use the stock tk-8.5 that comes with OS X 10.6.
Is there any way for me to check the system Tk dylibs to see whether
they were compiled with this flag?

   David
