i went and got a previous version and that worked.
it would be wise to make available on the mac download page a choice of downloads, one for PPC and one for Intel with a direct link for each. Not everyone has a new mac, and it should be made easier for those folks to know that it won't work for them. Hopefully the PPC version can get some updates as time goes on as well. I also miss the package installer, not that im afraid of the terminal, but i vastly preferred installing the older version. The command line is not something i use a lot on my mac.
