How to install pyobjc on activepython 2.6 for snow leopard?

I need json, pyobjc and ideally psyco as well.

I got all but pyobjc working on active python 2.6. How do I successfully install pyobjc properly?

Thank you.

I ended up installing it with easy install:

easy_install-2.6 pyobjc==2.2

That worked.
