Proper input matching design with purely reactive components will allow 
you to match ANY impedance to 50+j0 Ohms.  Even purely resistive loads 
can be matched in this way.  Follow it using a Smith chart if you doubt.

No, you can't compensate with a *single* component, but you most 
certainly can design a matching network for it so that your rig will 
"see" 50 Ohms.
