Bug#569920: libcairo-perl: fails to load with new libdirectfb

[Jonathan Yu]

Package: libcairo-perl
Severity: grave
Justification: renders package unusable


This package seems to be unusable with the newest version of
libdirectfb.

Building Graphics::Primitive::Driver::Cairo yielded the following
test output (see libgraphics-primitive-driver-cairo-perl in the
Debian Perl Group repository):

t/00-load.t ............ 
Dubious, test returned 1 (wstat 256, 0x100)

Inspecting the package in a chroot, a different API version of
libdirectfb is now installed. I'm not sure how to proceed here,
except perhaps conflict with the newer version or rebuild.

A rebuild of the Cairo bindings (libcairo-perl) should fix it,
but moving forward, I'd like to investigate a more robust and
resilient system (that won't result in breakages whenever a
new version of libdirectfb is uploaded).

After installing libcairo-perl (including directfb which is one
of the dependencies), the following files are put in /usr/lib:
  # ls /usr/lib/libdirectfb*
  /usr/lib/libdirectfb-1.2.so.9  /usr/lib/libdirectfb-1.2.so.9.0.1

The same error happens trying to load Cairo:
  # perl -MCairo -e1
  Can't load '/usr/lib/perl5/auto/Cairo/Cairo.so' for module Cairo: libdirectfb-1.2.so.0: cannot open shared object file: No such file or directory at /usr/lib/perl/5.10/DynaLoader.pm line 193. at -e line 0
  Compilation failed in require.
  BEGIN failed--compilation aborted.
