Errors Building xserver-xfree86

["Kevin Smith" <kevin@netsmith.ltd.uk>]

Hi All,

What does this error message mean when building xserver-xfree86?  I
compiled my own Kernel 2.4.20 for the powerpc for Debian Woody 3.0r1.
DId I miss or so something wrong with the Kernel compilation?

Skipping unpack of already unpacked source in xfree86-4.1.0
dpkg-buildpackage: source package is xfree86
dpkg-buildpackage: source version is 4.1.0-16
dpkg-buildpackage: source maintainer is Branden Robinson
<branden@debian.org>
dpkg-buildpackage: host architecture is powerpc
dpkg-checkbuilddeps: Unmet build dependencies: kernel-headers-2.4
dpkg-buildpackage: Build dependencies/conflicts unsatisfied; aborting.
dpkg-buildpackage: (Use -d flag to override.)
Build command 'cd xfree86-4.1.0 && dpkg-buildpackage -b -uc' failed.
E: Child process failed


Also, where can I get this package from and what exactly is it called in
apt:

warning: process set to nice value 0 instead of -10 as requested
X: /lib/libc.so.6: version `GLIBC_2.3' not found (required by X)


Many thanks,

Kevin
