The problem is that <find-shared-library> is not supposed to be used by
users -- it's not even feature in V2. The docs should describe prebuilt 
libraries, and the <library> property, which are the solution.

lib X11 : : <name>X11 ;
exe hello : hello.cpp : <os>LINUX:<library>X11 ;

Let me know if this works for you.
