The perl-after-upgrade utility makes -this process mostly unnecessary. - -The tool goes through the list of installed packages, looks for those -that depend on perl, moves files around, modifies shebang lines in those -scripts in which it is necessary to do so, tries its best to adjust -dynamically linked binaries that link with libperl.so in the old path, -and updates the package database. - -After installation of the new perl is complete, either by hand from the -ports collection, or from a package, or via portupgrade, do the -following: - -=over 4 - -=item o go root; - -=item o run perl-after-upgrade utility. - -Do not specify any arguments at first, so it does nothing destructive. -Pay attention to the produced output and especially to errorlist at the -end, if any; - -=item o run the utility again, with B<-f> command line option. - -This will actually do the work. Again, pay attention to the output -produced; - -=item o fix any reported errors; - -=item o reinstall required packages: - -The utility will tell you what packages that depend on perl it could not -handle. It will also tell you why it happened (for example, they were -compiled against a binary incompatible perl). If you want such packages -to remain operational, you will have to reinstall then by hand or via -portupgrade. - -=item o review the files left in the older perl installation. - -This is typically /usr/local/lib/perl5/site_perl/5.X.Y/. There should -be very little, if any, files in that directory and its subdirectories, -excepting a number of .ph files; - -=item o check that things work as they should; - -=item o remove backup files from the package database. - -Those will be /var/db/pkg/*/+CONTENTS.bak; - -=item o that's all. - -=back - -=head1 COPYRIGHT AND LICENSE - -Copyright 2005 by Anton Berezin - - "THE BEER-WARE LICENSE" (Revision 42) - <tobez@FreeBSD.org> wrote this module.
