Can't get neocomplcache to work.

Hi,

I installed neocomplete with vundle but everytime i hit the enter key i get this error :

Error detected while processing function <SNR>7_my_cr_function: line    1:
E117: Unknown function: neocomplcache#smart_close_popup
Press ENTER or type command to continue
Error detected while processing function <SNR>7_my_cr_function:line    1:
E15: Invalid expression: neocomplcache#smart_close_popup() . "\<CR>"
Press ENTER or type command to continue

Here is the configuration i'm using. Can you help me fing anything wrong i'm doing?

        \ }

I don't understand because i'm using a .vimrc file (https://github.com/diokey/myvimconfig/blob/master/.vimrc) that works perfectly on another machine. My vim version is 7.3.429 and it's running on Ubuntu 12.04

Thanks
