smarty template compile directory not writable

i'm using the latest version of smarty (3.0rc3). i made my templates_c directory writable in command line (chmod -R 777 templates_c) but smarty still outputs this when i call $smart->utility->testInstall();

Testing compile directory...
FAILED: ./php/classes/smarty/templates_c/ is not writable.
Warning: rename(/tmp/wrtub1GxS,./php/classes/smarty/templates_c

and this when i use smarty
