How to install hacked libgtk+2.0-0?

[Adam <ack94598@yahoo.com>]

I wish to install a hacked libgtk+2.0-0.  I already installed the 
package, so I think I do not need to use equivs, I can just copy the 
files to the appropriate places (of course when I do an upgrade I will 
lose the changes but that is ok).  Should I just do a 'make install' in 
my (hacked) upstream/tarballs/gtk+-2.2.0 and it will do the right thing? 
 If not what should I do?

Please send email as I do not subscribe to this list.  Thanks,
