Doug, I might have my terminology mixed up, but I think that when you 
compile something even as simple as hello world, at least on Linux (and 
I'm sure most other *NIX variants), you're using a runtime library 
(glibc on Linux.)  All you need to do is include the header file for 
crypt and use the functions it provides and the compiler will take care 
of dynamically linking the executable for you.  If you really want to 
statically link it though, there's an option you can pass to gcc that 
will do so (I'm not sure what that is though.  I'm sure someone else can 
help with that :)
