The port ‘lang/perl5.10’ was removed on 2013-02-04 because: “Has expired: no longer under development, use lang/perl5.16 or lang/perl5.14”. So we need to move from older 5.10 to newer 5.14. To upgrade perl choose port managment tool you like ( portupgrade or portmaster).
1) Fix pkgdb.db (for safety):
$ pkgdb -Ff
2) Reinstall new version of Perl (5.12):
$ env DISABLE_CONFLICTS=1 portupgrade -o lang/perl5.12 -f perl-5.10.\*
3) Reinstall everything that depends on Perl:
$ portupgrade -fr perl
$ portmaster -o lang/perl5.12 lang/perl5.10
$ portmaster p5-
Comprehensive (but perhaps overkill):
$ portmaster -r perl-
Note: If the “perl-” glob matches more than one port you will need to specify the name of the Perl directory in /var/db/pkg explicitly.
And now you can check which version of perl do you have:
