[support] new installation of Drupal 5 not finding gd

[Miles Fidelman]

Hi,

I just installed a brand new Drupal 5, on a Debian Sarge box.

The admin script is reporting "The GD library for PHP is missing or 
outdated" (everything else reports ok).

The thing is, I think I have gd installed properly and as up to date as 
the current package library provides (apt-get upgrade php4-gd reports 
that I'm up to date).

So... any thoughts or suggestions?
- do I need a later version of gd?
- is it perhaps something in the search path (pointers or diagnostic 
suggestions much appreciated)
- what doesn't work if I don't have gd properly installed?

Thanks very much.

Miles
