php accelerator for ppc?

[bronto]

I've been hearing very good things about php accelerator from other 
php developers.  This is a php module that caches scripts on your 
server (as opposed to caching the *output* of scripts).  I went to go 
and install it, but there doesn't seem to be a ppc version.  I've 
contacted the developer about porting it (it free, but not GPL), but 
I'm wondering if there are any other alternatives that will work for 
YellowDog.

Thanks

Rob
