Perl 5.16, as any other new perl version, requires all modules that are not purely perl code to be rebuilt. We did that for all packages in our repos.
For a list of upstream changes please refer to `man perldelta`.
Package changes: - Fix FS#27173 - [perl] Remove RPATH
Since users probably installed some from AUR or with CPANPLUS::Dist::Arch, I wrote a script that generates a local rebuild list. - raw.txt contains a list of files that generated an error - perl-modules.txt contains a list of modules the files belong to (not mapped to distributions; I'd gladly accept a fix for that) - pacman.txt contains a list of pacman packages the files belong to
Binaries linking with libperl.so will also need to be rebuilt. You can use lddd from devtools to find those.
Please report any issue you encounter.
