debian php apache and libxslt

[jez]

HI there,


I am trying to install php on an apache server running on debian.

The ./configure trips over on the check for libxslt
error:
checking for libxslt version... configure: error: libxslt version 1.0.18 or greater required.


but when i apt-get install this lib and the dev version I am told that i already have the latest version.
I have added sources to apt that say they have a later version but they dont seem to be installed.


Can anyone shed light on this, as i looks to me like debian only has an old offical package for this (1.0.16).

Thanks

Jez
