Topic: Upgrading perl
I had to upgrade perl 5.12.4 to 5.12.5...
# cd /usr/local/lib/perl5/site_perl/5.12.4/
# find ./A* -type f | xargs -J % pkg_which | xargs -J % portmaster -d -B -P -i -x gcc-4.6... -R % && cd /usr/local/lib/perl5/site_perl/5.12.4
That way was easiest (except for some ( /.D* for example) which had stray files so started to
rebuild thousands rather than just 1, 10, 20... at a time, easily remedied ..).
I expect to use that as a template should I upgrade, say, python27 to python28, etc...
