I'm trying to install the debugger extension Xdebug
[xdebug.org] for PHP on Apache running on my local Mac. I tried the built-in PHP installation and also the Entropy PHP package
[entropy.ch]. I got the extension from the Xebug site and also a precompiled version from Komodo
[code.activestate.com]. It's a PPC Mac and the extension is said to be universal binary, i.e. works on PPC Macs.
Xdebug never shows up in the phpinfo(); output, even though it loads the correct php.ini file (double-checked in output) and the .ini file specifies the extension correctly.
No matter what PHP/Xdebug combo, when I restart Apache, I see something like this in my error log:
[Fri Mar 04 12:26:49 2011] [warn] Init: Session Cache is not configured [hint: SSLSessionCache]
Failed loading /usr/local/php5/lib/php/extensions/no-debug-non-zts-20060613/xdebug.so: (null)

Is there any way to get more info about why it failed loading? The error message just says (null) - not very helpful. Any other ideas?
