Why/how are you trying to create a statically linked binary? As the  
message above explains, statically linking libdl relies on a bunch of  
library magic. At the very least you'll probably also have to link  
libc explicitly, but I would really recommend to link dynamically  
instead. Support for binaries statically linked against C libraries is  
generally very much untested, and known not to work on certain  
platforms (e.g. Linux/x86-64).
