[xdebug-general] Cannot hit breakpoints

I'm using NetBeans 6.9 and xdebug 2.1.0 on ubuntu9.10

I've installed xdebug successfully, at least according to the wizard,
which tells me:

    Tailored Installation Instructions
    Summary

        * Xdebug installed: 2.1.0
        * Server API: Command Line Interface
        * Windows: no
        * Zend Server: no
        * PHP Version: 5.2.10-2
        * Zend API nr: 220060519
        * PHP API nr: 20060613
        * Debug Build: no
        * Thread Safe Build: no
        * Configuration File Path: /etc/php5/cli
        * Configuration File: /etc/php5/cli/php.ini
        * Extensions directory: /usr/lib/php5/20060613+lfs

    You're already running the latest Xdebug version

I get "the pretty orange-bannered" reports about problems encountered
but I cannot stop on lines in the debugger.

When I debug the project in NetBeans the "Waiting for
Connection(netbeans-xdebug)" sliders wanders back and forth aimlessly
until I kill, at which point it pops up the xdebug-not-installed message
(attached) but I've set all the properties it mentions in both php.ini
files in etc/php5/{cli/apache2}/php.ini as

    xdebug.remote_enable=1
    xdebug.remote_handler=dbgp
    xdebug.remote_mode=req
    xdebug.remote_host=localhost
    xdebug.remote_port=9000

Any advice appreciated.
