php4-gd2 debian package problem

[Robin Kilpatrick <rak3@kent.ac.uk>]

Using unstable/testing...

The log file shows this problem, while the page half renders and stops 
half way through.

/usr/sbin/apache: relocation error: /usr/lib/php4/20020429/gd.so: 
undefined symb
ol: gdFreeFontCache

This was installing the php4-gd2 package, the php4-gd package installs 
fine. Very frustrating!

Can anyone help?

Thanks,

Robin Kilpatrick
