gd library

[Paul Thomas <pthomas8589@gmail.com>]

I'm using grip lenny armel and trying to install the GD library, but I
get unmet dependencies. Here is the error:

debian:/home/user/v4l/fswebcam-20070108# apt-get install libgd2-xpm-dev
Reading package lists... Done

Some packages could not be installed. This may mean that you have
requested an impossible situation or if you are using the unstable
distribution that some required packages have not yet been created
or been moved out of Incoming.
The following information may help to resolve the situation:

The following packages have unmet dependencies:
  libgd2-xpm-dev: Depends: libfontconfig1-dev but it is not going to
be installed
                  Depends: libfreetype6-dev but it is not going to be installed
                  Depends: libjpeg62-dev but it is not going to be installed
                  Depends: libpng12-0-dev
                  Depends: libx11-dev but it is not going to be installed
                  Depends: libxpm-dev but it is not going to be installed
                  Depends: zlib1g-dev but it is not going to be installed
E: Broken packages

sources.list has the following lines:
deb http://www.emdebian.org/grip/ lenny main
deb http://http.us.debian.org/debian lenny main contrib non-free

Is this a "known" problem? Am I doing something wrong? How do I figure
out _why_ apt won't install the dependencies? The reason I need GD is
I'm trying to compile fswebcam which depends on GD. I had all of this
working in a regular sid debian arm system.

thanks,
Paul
