To get /opt/splix/cups/lib/filter added to the use the full path in 
"%define filternames ...":

%define filternames /opt/splix/cups/lib/filter/rastertospl2

A "%define filternames" directive without path always defaults to the 
executable directory (/opt/splix/bin).

You can use "%define filternames ..." to make the paths to the OPVP 
driver executable appear in the PPD.

This we should really do in LSB 4.0.
