Thanks, Jeff.

I've used the attached patch.
Now amarok complains much earlier, during startup I get a messagebox:

KLibLoader could not load the plugin:
amarok_collection-mysqlecollection
Error message:
Cannot load library /usr/pkg/lib/kde4/amarok_collection-mysqlecollection.so: (Shared object "libmysqlclient.so.16" not found)

This looks like I need a "-Wl,-R/usr/pkg/mysqld/lib/mysql" (that's
where I installed the libmysqlclient.so) when linking this object. Can
someone tell me how/where to add that?

I run cmake with:
-DMYSQL_LIBRARIES:PATH=/usr/pkg/mysqld/lib/mysql/libmysqlclient.so

Thanks,
 Thomas
