To upgrade from 5.6.x to 5.8.x (with no 5.8.x installed):
'portupgrade -o lang/perl5.8 lang/perl'
As mentioned previously, be sure to follow the directions in
/usr/ports/UPDATING. You may need to change the upgrade command
slightly to reflect you're coming from 5.6.x instead of an earlier
version of 5.8.x (change the 5.8.2 to 5.6.1 as below):
portupgrade -f `(pkg_info -R perl-5.8.4 |tail +4; \
find /usr/local/lib/perl5/site_perl/5.6.1 -type f -print0 \
| xargs -0 pkg_which -fv | sed -e '/: ?/d' -e 's/.*: //')|sort -u`
After rebuilding everything, you may want to finalize the upgrade by
cleaning out /usr/local/lib/perl5/ and /usr/local/lib/perl5/site_perl.
Due to incorrect plists, there may be some files left there from 5.6.x.
It might be a good idea to check that each file is present in the
5.8.x directory before deleting (as a sanity check for the upgrade), but
after the complete rebuild it should be safe to remove everything. The
goal is to completely get rid of the 5.6.x directories:
$ ls /usr/local/lib/perl5/
5.8.4 site_perl
$ ls /usr/local/lib/perl5/site_perl/
5.8.4
I've not had any problems with this method (used on many machines
running 4.10, 5.2.1, and -CURRENT), but it's best practice to have a
full backup before the upgrade as it touches on a huge chunk of the
system...
