If I understand the question correctly (it sounds like you just want the
surface rendered around your ligand, not the entire protein), you should
be able to do something like:

set mapradius 5.0, transparency 0.3, maptype 1;
set mapramp from red to blue through white;
drawsurf surf covering in residue 100;

so if your inhibitor is residue 100, it should draw the map named "surf" 
only when it falls within 5 angstroms from that residue.  Hope this helps.
