I haven't got that far yet but in my case I'll most probably either rename the problem guile libs and executables or link them. The 
libraries should have their natural names as they should be versioned and the devel packages will be mutually exclusive due to name 
clashes. /usr/bin/guile-snarf will have to be renamed but the "--program-suffix=1" switch appends a 1 to it during build, guile-tools has 
been replaced in guile 2.0.2 so it can simply be renamed back to guile-tools during install with no ill effect, guile-config is depreciated 
and no longer used so it can be deleted.
Basically as long as the other packages on the system don't use guile 2.0 executables and have been built against the libraries and the 
libraries install from their own package guile 1.8 can exist happily alongside guile 2.0. I'll send a link to my spec files in a couple of 
days but the rule is package the libraries in their own versioned package to accommodate the likes of gnucash and make everything else 
mutually exclusive ie. libguile1 can exist with libguile2 and guile 1.8 uninstalls guile 2.0. The $datadir files are versioned already as 
well. There's the pkgconfig file that can be easily manipulated if need be but that is part of the devel package anyway.
Hope this helps, I'll read it again when I wake up in the morning and correct 
anything stupid.
