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).
