What's almost certainly happening is your main libutil package is ending up 
empty; by default packages are not actually written out if they are empty (the 
-dev, -dbg and -staticdev are always written out). You can verify this by 
looking under packages-split under the workdir for the recipe 
(tmp/work/<architecture>/libutil/1.0.0-r0/). Either this is because files you 
want in the main package aren't actually being built, or they are ending up in 
one of the other packages. During do_package, the build system looks through 
packages in the order they are mentioned in the PACKAGES variable, and the 
first package whose FILES value matches the file gets the file (you can see the 
default values of PACKAGES and FILES in meta/conf/bitbake.conf). So either you 
need to fix it so that the right files are being produced/installed, or adjust 
PACKAGES / FILES as appropriate.

Cheers,
Paul
