[Maxim Rovbo]

catkin_make for v1.3.9 labeled commit (f139e17) fails with the following error:

/home/cronberry/catkin_ws/src/trac_ik/trac_ik_kinematics_plugin/src/trac_ik_kinematics_plugin.cpp: In member function ‘virtual bool trac_ik_kinematics_plugin::TRAC_IKKinematicsPlugin::initialize(const string&, const string&, const string&, const string&, double)’: /home/cronberry/catkin_ws/src/trac_ik/trac_ik_kinematics_plugin/src/trac_ik_kinematics_plugin.cpp:229:25: error: ‘base_link_’ was not declared in this scope while(link->name != base_link_)

v1.3.8 finishes building successfully.
