How to remove old version glib

[hce <webmail.hce@gmail.com>]

Hi,

I am running an old version debian 3.0 with old version glib 1.12.4 in
/usr directory. The "/usr" partition space is full, so I have to build
new version of lib-2.20.4 as well as other packages in another
partition /opt. Now I need to remove old glib 1.12.4 from "/usr", but
if I run following command, it will remove all other dependency tree
as well which will cause big problems. My question is how can I remove
old version libglib in /usr without remove other packages?

~$ sudo apt-get remove --purge libglib2.0-dev
