linuxgeek: [nslu2-linux] ipkg install php-apache "server returned error 404: HTTP/1.1 404 Not Found"

I am trying to install php-apache, but when I run ipkg I get the error below.

# ipkg install php-apache
Installing php-apache (5.2.12-2) to root...
Downloading http://ipkg.nslu2-linux.org/feeds/unslung/cross/php-apache_5.2.12-2_
armeb.ipk
wget: server returned error 404: HTTP/1.1 404 Not Found
Nothing to be done
An error ocurred, return value: 22.

ipkg_download: ERROR: Command failed with return value 1: `wget --passive-ftp

Failed to download php-apache. Perhaps you need to run 'ipkg update'?

Please can someone tell me what is wrong. I have tried accessing "http://ipkg.nslu2-linux.org/feeds/unslung/cross/php-apache_5.2.12-2_armeb.ipk" but also get the same 404 error.

Have the packages been built correctly? Are they still available?
