+perl sets C<$^X> where possible to a full path by asking the operating

+C<sysctl> with C<KERN_PROC_PATHNAME> if that is supported, else by reading

+either approach sometimes returns an incorrect value
 (see http://www.freebsd.org/cgi/query-pr.cgi?pr=35703 ).
 In these cases perl will fall back to the old behaviour of using C's
 argv[0] value for C<$^X>.

-Not as bad as it sounds--what this means is that Perl will no longer be
-part of the B<kernel build system> of FreeBSD.  Perl will still very
-probably be part of the "default install", and in any case the latest
-version will be in the ports system.  The first FreeBSD version this
-change will affect is 5.0, all 4.n versions will keep the status quo.
