For those who got r540 and is on a Panther system, here's a direct link to the previous build: http://macromates.com/textmate/build/TextMate_r528.tbz

I do plan to continue with Panther support, but with the current developer tools, it seems to be Panther or i386, but not both, if I want to use libcurl -- it may take a day or so before this is sorted out. Meanwhile the auto-update won't let Panther systems update to r540.
