fwknop and perl5 upgrade

[Blair Zajac]

This relates to the perl5 upgrade to the default 5.12 variant.

fwknop relies upon Digest::SHA1, which doesn't come with perl 5.8, but  
does with 5.12.  So I can have fwknop depend upon perl5.12 instead of  
perl5 so I can remove the p5-digest-sha1 dependency, but even if I  
depend upon perl5.12, that doesn't mean that the other p5-* ports I  
depend upon are compiled against 5.12 and not 5.8, which happened to  
me and broke fwknop.  To I had to do the following

ports=`port installed p5-\* | grep p5- | awk '{print $1}' | xargs`
for p in $ports; do port -f uninstall $p; done
port -f uninstall subversion-perlbindings
for p in $ports; do port -f install $p; done

Suggestions welcome.

It does appear that we need p5* ports to be like the py25-*, py26-*,  
etc, which would be a pain.
