xulrunner ships its own copy of cairo

xulrunner is ahead of ubuntus cairo. so this won't be possible atm.

next upload will fix this. The xulrunner-1.9.dev + .head branch already default to system-cairo

This bug was fixed in the package xulrunner-1.9 - 1.9~b3~cvs20080101t1000+nobinonly-0ubuntu1

---------------
xulrunner-1.9 (1.9~b3~cvs20080101t1000+nobinonly-0ubuntu1) hardy; urgency=low

  * happy new year release for hardy (1.9b3 pre, CVS 20080101t1000) features:
    - use system-cairo (LP: #152210, LP: #164640)
    - use system-nspr/nss (LP: #177280)
    - proper pkg-config files for -unstable and system-nspr/nss (see below)
    - backed-out microb changes (back to square zero)
    - fix various embedding issues (see below)

  [ Fabien Tassin ]
  * Disable bz404634_att290373.patch and bz373196_att281782.patch until trunk
    is back in shape after the MicroB mass back out (See MozBug #408238)
    - update debian/patches/series
  * new upstream snapshot (1.9b3 pre, CVS 20071228t0918)
  * Drop patch committed upstream:
    - drop debian/patches/bz287150_att291740_hppa_fix.patch
    - update debian/patches/series
  * Add support for mozilla-devscripts
    - update debian/control
    - update debian/rules

  [ Alexander Sack ]
  * drop patches for mozilla bug #404634 completely to prepare landing of
    improved patch:
    - drop debian/patches/bz404634_att290305.patch
    - drop debian/patches/bz404634_att290373.patch
    - update debian/patches/series
  * land improved patch for mozilla bug #404634 that properly disables
    url-classifier if no profile is setup and makes nsUrlClassifierDBService
    fall-back to NS_APP_USER_PROFILE_50_DIR if NS_APP_USER_PROFILE_LOCAL_50_DIR
    is not provided by embedding app.
    - add debian/patches/bz404634_att294921.patch
    - update debian/patches/series
  * remove bz373196_att281782.patch completely from tree as it tackled a MICROB
    regression, which should now be fixed.
  * add %FULL_NSPR_CFLAGS% to libxul-embedding* Cflags .pc files to fix
    builds of embedders that link against system-nspr enabled xul
    - update debian/patches/bzXXX_pc_honour_system_nspr_nss.patch
  * do not export zlib headers with bogus symbols during make install if
    system zlib is used. This breaks embedders and happens if MOZ_INSTALLER
    is enabled.
    - add debian/patches/bzXXX_no_zlib_export_if_native.patch
    - update debian/patches/series
  * drop mozilla-devscripts from build-depends as its not needed for the
    actual package build process. Take care that debian/rules disables the
    mozilla-devscripts include if it doesn't exist
    - update debian/control
    - update debian/rules
  * add gtkmozembed_internal.h symbols to glue (mozilla bug 373918):
    - add debian/patches/bz373918_att295042.patch
    - update debian/patches/series
  * add support for GRE extensions and plugins. We now search in PROFILE, APP
    and GRE dir.
    - add debian/patches/bzXXX_gre_extension_plugin_support.patch
    - update debian/patches/series
  * explicitly create addon directories /usr/lib/xulrunner-addons/{plugins,extensions}
    - update debian/xulrunner-1.9.dirs
  * drop hard-coded --with-system-nspr and --with-system-nss from CONFIGURE
    flags
    - update debian/rules
  * don't enforce lower bound of system cairo and system nss versions
    - update debian/control
