How to successfully compile prozilla (proz) on Ubuntu Feisty (Geek Post)

If you get this error
download_win.h:55: error: extra qualification 'DL_Window::' on member 'print_status'
go to line 55 in src/download_win.h and replace it with
void DL_Window:: print_status(download_t * download, int quiet_mode);

(via LINUX... y otras cosas)
