Bug Description

Description: Ubuntu karmic (development branch)
Release: 9.10

To replicate:

$ sudo apt-get update && sudo apt-get upgrade
$ sudo apt-get install libcairomm-1.0-1 libcairomm-1.0-dev

libsigc++ should have been installed when libcairomm* was requested but was not.

So, when trying to configure a package with pkg-config this fails:

$ pkg-config --exists 'cairomm-1.0'
dane@ubuntu:~/src/mapnik-trunk$ pkg-config --libs 'cairomm-1.0'
Package sigc++-2.0 was not found in the pkg-config search path.
Perhaps you should add the directory containing `sigc++-2.0.pc'
to the PKG_CONFIG_PATH environment variable
Package 'sigc++-2.0', required by 'cairomm', not found

Manually running works:

$ sudo apt-get install libsigc*

$ pkg-config --libs 'cairomm-1.0'
-lcairomm-1.0 -lcairo -lsigc-2.0

This is affecting the python-mapnik package when installed from apt-get packages.

>>> import mapnik

leads to:

ImportError: /usr/lib/python2.6/dist-packages/mapnik/_mapnik.so: undefined symbol: _ZN6mapnik19cairo_renderer_base7processERKNS_15text_symbolizerERKNS_7featureINS_8geometryINS_6vertexIdLi2EEEEEN5boost10shared_ptrINS_6rasterEEEEERKNS_14proj_transformE

Uninstalling the python-mapnik package, after installing libsigc++, then reinstalling python-mapnik fixes the above undefined symbol error.
