Hi,
-lssl is listed in the LIBS parameter to Makefile.PL. This is not necessary as DSA.xs does not use any of the libssl's symbols.
The Debian package builds fine with -lssl removed (on all 12 architectures Debian supports, as well as on the unofficial Hurd and kFreeBSD ones).
The patch is really trivial, but I am attaching it here.
Thanks,
dam
