Package: perl Version: 5.22.1-8 When attempting to build perl-5.22.1-8 on a system that has an old version of perl currently installed (not cross compiling), the build fails with:

BEGIN failed--compilation aborted at debian/fixheaders line 7. make: *** [install-stamp] Error 2 dpkg-buildpackage: error: fakeroot debian/rules binary gave error exit status 2 I believe this error is not seen in official builds, because a previous version of perl-5.22 is already brought in through circular dependencies, and hence the (older version) standard library can be found in /usr and used at this point. However it fails when doing a build on a system that doesn't yet have perl-5.22, and I imagine you'll see the same failure in Debian next time the perl version number is bumped beyond 22. I imagine this problem was introduced here: http://anonscm.debian.org/cgit/perl/perl.git/commit/debian/rules?id=494019582d1007c831e65876dadd258874c9bd91 -I $(srcdir)/lib is no longer passed to PERL_TO_USE.
