phpwiki configer with apache 2.0..?

hi users..


i have a problem in configuring phpwiki with Apache 2.0

mysql version is 3.23.54, php 4.2.2

i able to get the index.php page and from there onwards i am not able to get the urls of the other pages
instead
when i click the links on this page i get the same page.

more details are

document root is /var/www/html
i have installed phpwiki-1.2.3 in /var/www/html/

so when i type http://server-name/phpwiki-1.2.3/
i am able to get the index.php page ...

what i found is that i need to do some changes in .htaccess file

i used "locate .htaccess" to find it
but i was not able to find it out..!
so does it mean that the files does not exists.. and if this is case than

can i make a new file..?

help needed...? or suggestions

i got these info from the link http://phpwiki.sourceforge.net/phpwiki/PrettyWiki

Thanks in advance...
