No comments from upstream, so I suggest it's now an appropriate moment
to get on and fix the individual packages (if we want to get the perl
5.14 up and running).

The current list, based on my rebuilds this weekend, is:

- hivex
- libapache2-mod-perl2
- libcrypt-gcrypt-perl
- libgd-gd2-perl
- libogre-perl
- libois-perl
- libpdl-io-hdf5-perl
- libpdl-netcdf-perl (doesn't actually fail, but seems to carry on
  even though the build fails)
- subversion (#628507)

Given the lack of action upstream so far I don't think we should yet
implement EXTRACCFLAGS yet, but I do think we should patch our perl with
the documentation patch.

Possible template bug report text for the broken modules:

--------
As discussed on Debian bug #628522, this package fails to build with
perl 5.14.1 because $Config{ccflags} is being overridden by local
CCFLAGS options:

<insert build log snippet>

This bug is also discussed upstream at
<https://rt.cpan.org/Public/Bug/Display.html?id=68613>.

Please modify the build system of this package to include $Config{ccflags}
into CFLAGS. In most cases this will be by editing Makefile.PL.
