hardcoded dependencies problem with building/installing GTK+

[Qing Men <maggie eclipse gmail com>]

Hi, 

I downloaded GTK2.16.4 and 10+ other packages that GTK 2.16.4 depends on. And did the following to make my application use GTK2.16: 

1. "configure --prefix=my_build_dir" 
2. "make" 
3. "make install". 
4. cp my_build_dir/lib my_install_dir/lib 
5. set the environment variable LD_LIBRARY_PATH to my_install_dir/lib before running my application. 

My application runs fine so long as my_build_dir/ is still accessible. On a host where my_build_dir is not accessible, the application runs into problems. 

One of the problem is with my_build_dir/lib being written into the library as RPATH. I fixed that by patching the libtool according to http://wiki.debian.org/RpathIssue. 

But I'm now facing with another problem. The application would try to look for "my_build_dir/etc/gtk-2.0/gdk-pixbuf.loaders" and "my_build_dir/etc/pango/pango.modules" and complains when not found.

How to prevent my_build_dir from being written into the library? In particular, how could I make my application look for the gdk-pixbuf.loaders and pango.modules in my_install_dir instead of my_build_dir? 

Thanks
