Beware that 'libxxxx.so' is only a symbolic link to the actual library, 
that is installed by the development package of the library.

So if you don't install the development package, you don't have the link.

You have normally two other library files installed by the library 
package (not the development one).

For example, for "libGL", you have "libGL.so.1" and "libGL.so.1.7.0". 
"libGL.so.1.7.0" is the actual library , and "libGL.so.1" is a symbolic 
to it.

It's there because ".7.0" is usually a bug fix version number where the 
public interface of the library does not change.

So you should use "libGL.so.1" to always get the latest version of the 
first version of the libGL public API.

Of course, I can't ensure that you have the same "libGL" library version 
number everywhere. It would be too easy. You must check!
