Trouble installing vidalia package

[Gavin <qwert98765@xxxxxxxxxxxxxxx>]

Hi,

I've been trying to install Tor on a Mac (ibook G4 OSX 10.3.9) but for 
some reason can't get the installer package to open. The message I get 
is;   "vidalia-bundle - 0.1.2.18-0.0.14-panther" cannot be opened. 
There was an unknown error with the package (999)"

I downloaded the Panther package from the 2 links below but neither 
worked. If someone could give me a pointer as to what might be wrong 
and how I could get it to open I'd appreciate it. Thanks
