No, those are not the same. The Zend Engine is of course fine to have.

I think it's the problem as well. You seem to have the ionCube PHP
Loader loaded, which is also a Zend extension. I am sure that if you
unload it, Xdebug will load fine. I'll update the docs to include the
ionCube loader as possible culprit.

It's just because you started apache from that directory... nothing
strange :)
