Q: skype wont work with my mac os 10.5.8

Your Mac is too old to run it.

Click the system requirements on that page & you will see…

• 1GHz Intel processor.
• Mac OS X 10.5.8+.
• 100 MB free disk space.
• Either USB or regular headset if your Mac does not have a built-in microphone.
• Download drivers if you are using an external webcam.
• For voice calls recommend broadband connection with 100 kbps down / 100 kbps up.
• For group video calling everyone on the call needs Skype 5.0 for Windows or Mac or higher plus webcams. For best quality we recommend you use a high-speed broadband connection of 4Mbps down/512kbps up and a computer with a Core 2 Duo 1.8 GHz processor. As a minimum you’ll need a high-speed broad connection of 512kbps down/128kbps up and a computer with a 1 GHz processor.

Your Mac has a Power PC processor not an Intel CPU.

Skype 2.8 from 2011 is the final version that works with G4, G5, and OS X 10.3.9 and later.

You can get it here by using Skype's webpage from the Wayback Machine archived web page:

Skype (v.5 or later) is for Intel Macs running OS 10.5.8 or above only.

And from September 2014 no more Skype for PPC Macs:
