- 'make test' failed under perl 5.5 because some prequisite
modules were not found. So now I added all requirements
to Makefile.PL, even if those modules are part of
recent perls (beginning with 5.6). I could have also
added a 'use 5.6' to the code but this would users
of perl5 exclude. This way they have the possibility
to fix their installation. Hopefully.
No code changes otherwise.
