Sorry I should have mentioned that ghostscript are integrating colour 
profiling using icc profiles although the last time I checked there was no 
support for the kind of monitor profile creation devices such as those 
manufactured by datacolor which I use on I hate to say it MS$ systems. There 
is an interesting paper on Ghostscript Color Management to be found on 
www.artifex.com/Ghostscript_Color_Architecture.pdf
