Bug#795741: libopengl-perl: FTBFS: undefined symbol: glResizeBuffersMESA

[Niko Tyni]

Package: libopengl-perl
Version: 0.6704+dfsg-1
Severity: serious
X-Debbugs-Cc: libgl1-mesa-glx at packages.debian.org

As noticed by the reproducible builds CI setup, this package fails to
build on current sid.

  #   Failed test 'require OpenGL;'
  #   at t/00_require.t line 3.
  #     Tried to require 'OpenGL'.
  #     Error:  Can't load '/«BUILDDIR»/libopengl-perl-0.6704+dfsg/blib/arch/auto/OpenGL/OpenGL.so' for module OpenGL: /«BUILDDIR»/libopengl-perl-0.6704+dfsg/blib/arch/auto/OpenGL/OpenGL.so: undefined symbol: glResizeBuffersMESA at /usr/lib/x86_64-linux-gnu/perl/5.20/DynaLoader.pm line 187.

It looks like mesa 10.6 dropped a bunch of symbols without changing the
SONAME. Copying the maintainer. Was this an intentional ABI break? 

On current sid, without rebuilding anything:

  # PERL_DL_NONLAZY=1 perl -e 'use OpenGL'
  Can't load '/usr/lib/x86_64-linux-gnu/perl5/5.20/auto/OpenGL/OpenGL.so' for module OpenGL: /usr/lib/x86_64-linux-gnu/perl5/5.20/auto/OpenGL/OpenGL.so: undefined symbol: glResizeBuffersMESA at /usr/lib/x86_64-linux-gnu/perl/5.20/DynaLoader.pm line 187.

This is also
  http://sourceforge.net/p/pogl/bugs/21/
  https://bugzilla.redhat.com/show_bug.cgi?id=1224294

which have the attached patch that deletes references to the
removed symbols. Even with that applied, I suppose at least
some Breaks entries would be in order?
