I've been using ZendDebugger with Eclipse (on OS X) for a while now and it works great!
Here's the recipe that's worked well for me.
- install Eclipse PDT via "All in one" package at: http://www.zend.com/en/community/pdt
- install ZendDebugger.so (http://www.zend.com/en/community/pdt)
- configure your php.ini w/ the ZendDebugger extenssion (info below)
- edit php.ini
add the following:
Now run "php -m" in the command line to output all the installed modules. If you see the following then its installed just fine
[Zend Modules] Zend Debugger
Now restart Apache so that it reloads PHP w/ the ZendDebugger. Create a dummy page with in it and examine the output to make sure the PHP apache module picked up ZendDebugger as well. If it's setup right you will see something like the following text somewhere in phpinfo()'s output.

OK - but you wanted Aptana Studio... at this point I install the Aptana Studio Plugin into the PDT build of Eclipse. The instructions for that are at: http://www.aptana.com/docs/index.php/Plugging_Aptana_into_an_existing_Eclipse_configuration
That setup has served me well for a while - hopefully it helps you too
