PHP API not matching

PHP API not matching

I need to enable a module installed on my system. I have installed PHP 5.4
from ondrej's repository couple of months ago ago and now I have compiled
ODBTP module from the source.
Unfortunately, if only I enable this module I receive an error causing all
the PHP scripts failure:
PHP Warning: PHP Startup: odbtp: Unable to initialize module
Module compiled with module API=20090626
PHP compiled with module API=20100525
These options need to match
in Unknown on line 0
I think i understand what it's trying to tell me, I wanted to compile PHP
from source, so that it would have matching version of API, however I
can't find the source for my version of PHP...
If you need any more details, I will be glad to provide them.
