1) (Biggest) I tried long-and-hard to keep the version number (5.006)
backwards compatible with FreeBSD; I have lost this battle, and
must defer to the Perl convention (5.6.0). Victims include suidperl.
this means that dirs with a name of 5.006 will be replaced with
dirs named 5.6.0 in both /usr/libdata/perl and /usr/local/lib/perl.
2) Errno module is added.
3) Alpha bits extensively tweeked after a Beast-build.
Other commits to follow.
