"A security hole has been discovered in Safe.pm. When a Safe compartment
has already been used, there's no guarantee that it's safe any longer,
because there's a way for code executed within the Safe compartment to
alter its operation mask. (Thus, programs that use a Safe compartment
only once aren't affected by this bug.)"

By default, the Perl module search order is "use lib, -I, PERL[5]LIB,
perl, site, vendor, other". This means that in OpenPKG both the modules
installed via CPAN shell (in "site" area) and the "perl-xxx" packages
(in "vendor" area) cannot override the (sometimes obsoleted) module
versions distributed with Perl (in "perl" area). Hence, we change
the search order to a more reasonable one for OpenPKG: "use lib, -I,
PERL[5]LIB, site, vendor, perl, other".

By default, the "vendor" area is not used, so Perl's installation
procedure forgot to create its top-level paths, too. In OpenPKG we use
the "vendor" area, so make sure it is created the same way the "site"
area is.
