how and where to install FUDforum under Apache2

[Thufir]

I'm trying to install http://www.fudforum.org/, and get:


	FUDforum Installation Wizard 	 

Please grant read/write permissions on this installation file () to the 
web-server user to proceed.

http://localhost/fudforum/install.php


The install files are as so:

thufir at dur:~$ 
thufir at dur:~$ ll /var/www/fudforum/

Now, this is under apache2.  Is the problem that I have this in the wrong 
directory?  Should it be in home somehow?  I'd rather not delve into 
Apache too much, and just use the Apache from apt-get.

Just some pointers on how get started, please.




thanks,

Thufir
