I think you are trying to compile eAccelerator for a new php version but didn't run phpize from the version. So the makefile is still using the old sources. The include path really works, the phpize script makes sure that the root source dir and the ext, main and Zend subdirectories are in the include path.

I saw this when compiling under windows using VC++. In the VC-project-file the ext-path is missing.
