seahorse versions 0.9.0 and HEAD both fail to compile when sharing is enabled:

../libseahorse/.libs/libseahorse-internal.so: undefined reference to `avahi_service_browser_new'
../libseahorse/.libs/libseahorse-internal.so: undefined reference to `avahi_service_resolver_free'
../libseahorse/.libs/libseahorse-internal.so: undefined reference to `avahi_client_free'
../libseahorse/.libs/libseahorse-internal.so: undefined reference to `avahi_client_new'
../libseahorse/.libs/libseahorse-internal.so: undefined reference to `avahi_client_errno'
../libseahorse/.libs/libseahorse-internal.so: undefined reference to `avahi_service_browser_free'../libseahorse/.libs/libseahorse-internal.so: undefined reference to `avahi_service_resolver_new'collect2: ld returned 1 exit status

The problem is a missing linker dependency, libavahi-client.so. [using avahi-0.6.9]

A patch is shown below.
