Perl 5.18 problems with mj2

I upgraded the perl on my Freebsd system to 5.18 and mj2 stopped working.

"make test" showed a lot of complaints, all of which turned out to be due 
to an incompatible change in the Safe module.  I made all the complaints 
go away by finding the places that call Safe (about six of them) and 
in the permit_only() call, I added the new "rv2gv" operator.

Unfortunately, it still doesn't work.  The symptom is that it doesn't send 
out any mail.  I'm using the qmail module, haven't had a chance to futz 
with it enough to pin things down in more detail.

R's,
John
