to trigger/signal a rebuild for the transition 5.8.8 -> 5.10.0.
The list of packages is computed by finding all packages which end
up having either of PERL5_USE_PACKLIST, BUILDLINK_API_DEPENDS.perl,
or PERL5_PACKLIST defined in their make setup (tested via
"make show-vars VARNAMES=...").
Path::Class is a module for manipulation of file and directory
specifications (strings describing their locations, like
'/home/ken/foo.txt' or 'C:\Windows\Foo.txt') in a cross-platform manner.
It supports pretty much every platform Perl runs on, including Unix,
Windows, Mac, VMS, Epoc, Cygwin, OS/2, and NetWare.
Needed for SVK-v2.0.0.
