	You are correct about libdl.so resoliving symbols. It allows your 
program to read in symbols from other .so files at runtime. There is 
only a .so version of it.  It is possible to have a program that is 
otherwise linked statically to be linked with libdl.so. You can choose 
which libs you want to be static and which to dynamic. You can have the 
standard libs, like those under /usr/lib linked dynamically, and have 
private libs linked statically. This way you can use the binary on 
machines that don't have your private libs.
