Thanks for the suggestions.  They did not work until I manually went out and cleaned \
up all remnants of Qt, PyQt and SIP and tried again.  It appears that the \
installation target of one or more does not overwrite existing files.  Also, SIP and \
PyQt have install targets in the makefiles, but no uninstall targets.

I am now running Qt 4.7.0, SIP 4.10.2, and PyQt 4.7.3 on Snow Leopard 10.6.3 64bit

Thanks for the help.
Rob
