[webkit-help] Webkit Platforms

[Joe McBride]

I use an Apple PowerPC, Dual 1.8GHz G5, with 2.25 GB DDR SDRAM. My OS  
is Mac OS X version 10.5.8.
I always download the nightly builds via the "search for webkit  
updates" function in the "Safari"  drop down menu.
Since July 7th, I have successfully downloaded the nightly build, but  
when I try to install, the Web Kit icon is greyed out and i get the  
message that this software is not supported by the architcure,
Is the PPC no longer a viable platform or unsupported or is this just  
a bug?
Either way, direction is appreciated as I misss WebKit ( back to using  
just Safari, which seems slow).
Thanks, in anticipation.
