apache localhost testing with permalinks problems

hi,

i was testing with the wordpress 2.5 on my apache 2.2.4 localhost
i tried permalinks using custom structure with
/%category%/%postname%/

in my apache httpd
i did enable mod_rewrite

but still it cant access to my page

inside my .htaccess in my wordpress folder, i see that
instead of
RewriteRule . /mylink/
it will becomes
RewriteRule . /mylink/index.php

but even i changed it to
/index.php/%category%/%postname%/
in my custom structure….it still get errors.
