Thank you for updating rpmmacros.
I tried it and confirmed it replaced "*cupsfilter" path by absolute path
I have no problem on my case, defining absolute path in filternames :)
But it adds "/opt/splix/bin/" directory to "*cupsfilter" if somebody define
only filename in "filternames" like
%define filternames rastertospl2
Because you changed code on related FoomaticRIPCommandLine.
I think it has to add "/opt/splix/cups/lib/filter" in ppd.

OPVP driver of IPC extention type.
It needs to load module and stream data such as following.
When they call next module, they use module name in these source file.
cupsfilter -> gs -> opvp ipc client library
-> opvp ipc server executable module -> opvp driver

Some drivers/filters executable path is NOT in the PPD file.
For example, path of opvp ipc server executable module is written in
Makefile.am of opvp ipc source.
Of course, it differs from one case to the next.
I think we may need a policy of the way to call executable modules,
changing path environment or using absolute path, or more way if you have.
