mplayer GUI install

[cga <cga2001@gmail.com>]

mplayer's "./configure --enable-gui" fails because I'm missing the GTK 
dev packages.

When I try to apt-get the GTK 2.0 dev library, apt informs me that it 
will remove the following:

 initrd-tools kernel-image-2.4.27-1-386

Does this mean that the 2.0 library is not compatible with my current 
kernel and that I should look for an older version?
