What is your Aperture version? Here is the list of supported raw formats for Aperture 3, see: Apple - Aperture - Technical Specifications - RAW Support
Your camera is not on the list. Use the software that came with your camera to convert your raw files to dng or tiff images; then you can import the images into Aperture and work with them, while waiting for Apple to release raw support for your camera. Or shoot raw+jpeg pairs and use the jpeg while you are waiting.
Is Mac OS X (10.5.1) really your current operating system? Then you may need to upgrade, when Apple finally releases raw support for your camera. The newest raw support required Aperture 3.4. to be installed.

Actually my iPhoto '11 is giving me the same problems for my Leica D-LUX 6 - unable to read my RAW files.

Right because RAW file decoding is a system level function in OS X. All Apple programs that access RAW files use the same code.
