I don't know exactly what your problem is, assuming you are not linking 
in any some unknown library expecting the __dso_handle symbol. Maybe you 
are not using the correct compile/link options for Perl. Have you tried 
running this same example which is under Examples/perl5/simple? It tries 
to get the correct compiler options from your perl installation for 
compiling perl extensions and so it might have all the compiler/linker 
flags correctly set up for you. If not, consult any perl documentation 
on how to compile perl extensions.
