'gd' PHP extension is not installed

I'm trying to install the Image_Color pear package. I keep getting the
following error:

"'gd' PHP extension is not installed"

phpinfo on my web server indicates that gd is enabled. when I try to
get info from my command line interface I don't see anything where it
was compiled with gd.

Am I right in assuming there are two ini files? One for the command
line and one for the web server?

A google search has revealed that others have run into this problem but
I have yet to find a solution.

Can anyone shed any light?

general info from the command line...

is it php 4 or 5? there is no official gd package for php5, that could
be the reason there are other unofficial gd extensions for php5 i
believe, try and download one and compile it, if your using php4 just
use your distros package manager to download and install it again, ie.
apt-get install gd-2
