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. David
