How set PHP_INCLUDE_PATH correctly in Textmate project

Question

Hi I'm trying to configure my Textmate project/env to be able to find included/required files.

I believe one way is to set a project specific environment variable PHP_INCLUDE_PATH.

As far as I know this should be colon separated, so something like this should be okay:

.:./src/:./src/mode/

But (command)+(shift)+d, that is 'Jump to included file' just reports: File not found.

Should I prepend TM_PROJECT_DIRECTORY? and how would i do that?

{$TM_PROJECT_DIRECTORY}: {$TM_PROJECT_DIRECTORY}/src/:{$TM_PROJECT_DIRECTORY}/src/model/
