patches for lang/perl5.8 dfport override

[Chris Pressey]

Hi,

Patches so that Perl5.8 can build.  I built it by putting these patches
into ports/lang/perl5.8/files.  The proper way to do it would be to make
a dfport override, but since no-one seems to know why my previous
attempt at making one of those doesn't work, this activity is left as an
exercise for the reader.  :)

I'll look into sending these upstream if I can find the time later
(pretty swamped right now...)
