Ok, I compiled of http://www.argyllcms.com/argyll_dev_src.zip successfully (is this the beta you where talking about? dispread version is 0.70 BETA4).
If you're using an unmodified HCFR, you probably want to change the calibration matrices appropriately - see about line 327 and 392 in hcfr.c. This only affects the brightness calibration.
How do I use 'dispread' to work with the HCFR probe?
The same as any other colorimeter instrument. See <http://www.argyllcms.com/doc/Scenarios.html> and <http://www.argyllcms.com/doc/dispread.html> or the equivalent provided with the source. Graeme Gill.
