jmoran,
I noticed you had the symlink for php53 pointing to the wrong binary. Not sure if this had anything to do with the problem you were having or not. But when I try with one of your domains to point to the php binary in your cgi-bin directory it processes the php.ini file there just fine. You have phpinfo disabled in that php.ini file so if you go test trying to use the function you will get an error message saying it's disabled.
Is there perhaps something else that isn't working that you think should be working ?
Feel free to pm me if you don't want to post exact details.
