I agree.

>(which is the libvtkzip.a referred to above).

Why?  I would suggest the opposite.  zlib is already included with the OS, and presumably QA'ed by Apple.  Why increase code bloat by building it again?  Also, Apple seems faster than the VTK community at updating zlib, as Lion contains 1.2.5 while VTK is still at 1.2.3.

If you use VTK_USE_SYSTEM_ZLIB, you'll of course need to link to Apples zlib in your Xcode project.

More precisely, any UI portions of Carbon are 32 bit only, including, I believe, AGL.

I definitely advise against using Carbon for any new projects.
