I don't know about preference settings, but I do know how you can verify at 
least if eog has been compiled with lcms support or not. That would save you 
the trouble to recompile.

There is a linux command ldd, which will show all libraries a given program is 
linked to. On my Fedora 10 box,
ldd /usr/bin/eog
will return a long list of libraries. The relevant line is this:
liblcms.so.1 => /usr/lib/liblcms.so.1 (0x02f4c000)
Which indicates that eog is compiled with lcms support.

Of course this doesn't mean eog really does something with the library. It 
only means recompilation probably wouldn't change anything.

I am only following this thread in the background, but is Milan Knízek's 
suggestion not an explanation for eog's behaviour ?
