Sorry to answer myself, but I figured it out (naturally) right after posting.

I have a new Mac Pro, and for some reason PHP validation won't work at all on it. I'm using a migrated user account from a Tiger machine, and I suspect that might be the problem, but I can't figure out what is setting it on the wrong path.
If I create a new test account, everything works perfectly in it. The default PHP command is used for validation, and errors are properly displayed.
I have tried setting and deleting the TM_PHP variable. I have created and destroyed a .MacOSX/environment.plist. I can't find anything else that would explain this on the web or this list. Any ideas?
I had an old copy of the PHP .tmplugin in my ~/Library/Application Support folder, and it was masking the built-in one. That's why a vanilla user could see PHP support using the native PHP binary and my migrated account could not.
