OK, it's all committed now.

No, just the SCons build. Actually I never tried the cmake build. What  
is the future for Lprof, will the two build systems coexist or will  
you eventually drop one of them?

I compared the old (qt3) and new (qt4) Lprof. The folder structures  
are the same and all files are where they belong:

lprof.app/MacOS
	assistant.app
	lprof (the actual binary)
	data (folder)
		help (folder, with 2 sub folders en, ru, html and other files inside)
		pics (folder, files inside)
		profiles (folder files inside)
		template (folder, files inside)
		translations (folder, files inside)
		spyd2PLD.bin (this is where I copy the Spyder driver file so the  
Spyder gets recognized...)

By the way, I tested the Spyder with this Lprof and it crashed when I  
tried to take readings for building the screen profile - same as with  
the old Lprof.

Yes, that was the problem: it was set to the SPR200 Super...icc  
profile. Changing that to some other profile solved the problem.

Interestingly I now changed the "Input Profile" to Wide Gamut RGB,  
then closed Lprof, removed this profile and re-opened Lprof. Lprof now  
choose the next available profile and did not crash. So the bug  
happens under some circumstances only.


I was able to "produce" another Lprof crash: under Camera/Scanner  
Profiler click the Select Directory button, then hit Cancel on the  
dialog displaying folders, then try do do something else like loading  
an image or selecting the reference file from the drop down: Lprof  
crashes.


Some other minor things I noted quickly going through the Lprof screens:
1) under Camera/Scanner Profile Parameters dialog -> general: the  
contents of the CLUT Resolution panel are very tightly spaced
2) under Camera/Scanner Profile Parameters dialog -> White point  
handling: the Location panel is not rescaling with the screen and the  
contents are a bit mis-aligned
3) under Camera/Scanner Profiler main screen: the Select Directory and  
Load Image buttons have a different look as all the other buttons:  
they are squared, all other buttons are rounded (the OS X default look)
4) under Monitor Profiler main screen: perhaps "Monitor" should be  
renamed to "Display" as some other screens use the word Display.... or  
the other way around...
5) under Display Profile Parameters dialog: the CLUT Resolution and  
Profile verbosity panels are very tightly spaced (as with point 1)
6) under Monitor Profiler main screen -> build coarse profile -  
Monitor values dialog: the "OK", "Help" and "Set Gamma and Black  
Point" buttons are squared (as with 3)
7) under Monitor Profiler main screen-> build accurate profile from  
measurements: both "Select Directory" buttons are squared (as with 3, 6)
8) under Monitor Profiler main screen-> build accurate profile from  
measurements -> Calibrate and Measure: the dialog that opens has no  
title
