This page is not current as it has things like links to patches for 
poppler-0.11.x which I think add CM support similar to what is in 
poppler-0.12.0 and later.   Most recent release is 0.16.2 and most distros 
will have version 0.14.4 or 0.14.5 as the stable version so no patches are 
required for most users unless they are running very old software.  

It has a section on GhostScript 8.64 when the current version is 9.0 although 
9.0 is not yet included in most distros as a stable version.  But it seems to 
me that any testing should be done using the latest version of GhostScript 
since this will likely be commonly used by the time the PDF printing work flow 
is in wide use.  Also I noticed that Ghostscript appears to create a 
pdftoraster filter.  To test this I just installed GhostScript-9.0 on my system 
(Gentoo so this is built from source) and it does create a pdftoraster as well 
as pstopxl and pstoraster filters.   Interestingly the ebuild also installed 
poppler-data-0.4.,4 as a package that GhostScript is dependant on.   Perhaps 
we should also test the GS V9 version of this as well since it may actually 
have better CM support than the poppler based filter (IE. maybe it supports 
rendering intent and/or uses the PDF OutputIntents to get the output profile 
for example).
