Comment 2 for bug 211991

As far as I am aware sigc++ 2.2.x is a new API version intentionally incompatible with sigc++ 2.0.x. The WorldForge sytem current uses sigc++ 2.0.x and will stay with this version for the time being. Sigc++ has historically used a runtime and compile time version model that makes it possible for application and library code to use one version while another version is installed for both runtime and compile time compatability. If this is a problem in Fedora 9 please update this bug accordingly and we will review our options.
