OK  thanks to you guys asking some questions I have found that 
graphics/lprof-devel
can support the creation of monitor and print profiles using Spyder 2 & Spyder 
3 from datacolor. I have been a bit lazy in following up my earlier interest 
in profiling monitors on freebsd 7.2 & 8.2 as I would like to reduce my 
reliance on MS$ and apple systems. It looks like I missed this one which is 
being compiled as I speak.

I will try forcing a compile of the 32bit code for the epson r2400 & r2880 
which I am told may compile on 64bit given some work. I will report back if I 
finish up with a viable system.
