Yep, I'm trying it on Leopard. I've tried it now on Lion and no luck, the Show Package Contents option didn't appear. But just right now, the unpkg method worked out perfectly.

That's quite informative and helpful. I will try it if I get no results using the unpkg method which was suggested by another user.

On finder, the Show Package Contents doesn't appear on right-click. Actually I had tried it before I send the post. By the way, the gcc3.3.pkg is available within the XCode-3.2.x

I will use those gcc3.3binaries to compile an old package. And it's easy to set it, i.e. GCC=/usr/local/gcc-3.3/bin/gcc before configuring. After I compile the package I'd like to be able to delete the gcc3.3 without messing with the present versions of the gcc which are (AFAICR) 4.0.1and 4.2.0 That's why I'd like to install it into a custom directory.

That would require too much time and the resulting binaries possibly would not be as good as the ones inside the gcc3.3.pkg

That's not easy because this BT card was manufactured in February 2002 and the OS X drivers were compiled at around 2005 and haven't got any update since then.

I've just tried connecting my Sony MH100 Bluetooth headphone. The pairing was okey but after the pairing when I selected "use headphone" on the Bluetooth menu, the computer just crashed i.e. I needed to press the power button for seconds to reboot the OS. So the BT drivers may not be perfectly working.

Thank you for the comment. The BT on the PowerBook works properly because once it's up and running, I can connect to any BT mouse or keyboard or whatever. On the picture, on the left is a connected BT mouse. And I can send files to Android 7 phone, as I've already stated on the message. So this Bluetooth card should be working fine. I haven't tried it with my BT headphones but I will give it a try soon. Yep the drivers are 3rd party as there were no OS X drivers coming with the card.
