	| owever regarding the correct file to use, I feel that you make it really hard: depending on the OS, 32/64 CPU, glibc version and PHP version the user needs to download a different tar.gz file | 
No, it's not we who made all the platforms imcompatible 
 
Try to run a binary compiled for 64bit Linux under 32bit one and you'll see weird results eventhough the Linuxes are of the same version/distribution!

You may want to try to adapt dbg-wizard script that detects platform and CPU and suggests correct debugger module. PhpExpress is available under almost the same platforms.

Sure, and glibc-2.7 modules will not be available in the next version.

no. It must be the same as php. If php is 32bit, phpextension should be 32bit. If php is 64bit, all its extensions must be 64bit too.
