Wanted to get this out there in case anyone else was having these issues.
Snow Leopard changed my PHP configuration. (In fact, it might have come with no php.ini set up altogether... I've already forgotten.) The configuration killed any bundles that ran PHP code (like the wonderful but quirky FTP/SSH bundle), since it was not passing environment variables from Textmate to PHP.
I was getting errors like: PHP Notice: Undefined index TM_PROJECT_FILEPATH PHP Notice: Undefined index TM_DIRECTORY etc.
and FTP/SSH reported "Remote settings file not found", when really that was the least of its problems.
The fix: * Make sure you have a file, /private/etc/php.ini -- you may have to copy or rename 'php.ini.default' * Search for the variables_order configuration line. It should be uncommented, and have an E in it, like this:
variables_order = "GPCSE"
