[PATCH 1/2] maint: require perl 5.6.2 throughout

[Stefano Lattarini]

That version of perl is quite old already, so it should be OK to
require it.  More importantly, it is the older perl versions the
developers can currently use for testing, thus it's safer and more
honest to just require it throughout.  And anyway, we were already
requiring it in Automake::Getopt, which implied that both automake
and aclocal wouldn't have worked in practice with an older perl
version.

See also the discussion related to automake bug#10925.

* configure.ac: Verify that the perl interpreter has at least
version 5.6.2.
* lib/Automake/ChannelDefs.pm: Adjusted to require perl 5.6.2.
