Unforbid the port for the use of general FreeBSD public.

Compile perl with BSDPAN support, both -current and -stable.  The
version of BSDPAN used here coincides accidentally with the one present
in the -current system perl, but is installed in a different place.

Provide a script, use.perl, to facilitate switching of the perl used by
default between the system perl and this port.  Also print a message
describing the usage of use.perl (this works for the port and for the
package built from it).  The switching to the port version is done by
removing /usr/bin/perl and /usr/bin/suidperl (they both have link count
>1, so this is reversible), and making them to be symlinks to the
corresponding binaries in $PREFIX/bin.  Also, assignments of the correct
values of PERL_VER, PERL_VERSION, and PERL_ARCH are appended to
/etc/make.conf.  Last, NOPERL=yes is appended to /etc/make.conf, so that
the changes made will survive system upgrades from source.  The
switching to the system version is more or less a reverse of the process
described above.

Set and use PERL_ARCH which is independed from the one used by the
system perl.

Fix the port for post-malloc.h -current.

Fix a small bogon when PREFIX was used in pkg-install (PKG_PREFIX should
have been used instead).

+Installation of Perl distribution is finished.  Please note, that since
+Perl is also in the base system, this distribution will not be used by
+default.
+
+If you want this version of Perl to be used by default, please type
+
+  use.perl port
+
+Assuming that use.perl script (which was installed with the rest of the
+Perl distribution) can be found in your PATH (you might have to type
+`rehash' first, depending upon a shell you use), this action will
+replace /usr/bin/perl and /usr/bin/suidperl with symbolic links to the
+versions of these binaries in the Perl distribution.  This action will
+also put some variables into your /etc/make.conf file, so that newly
+installed ports (not packages!) will use new version of perl, and the
+system upgrades from the source will not overwrite the changes made.
+
+At any time you can also type
+
+  use.perl system
+
+if you wish to revert back to the system version of perl.
