Changing the userid to "root" is not a good solution: It works
except for local installs, where this trick breaks the install:

$ make PLATFORM=linux PREFIX=~/chickentest install
[...]
install -d -o root -g root "/home/ckeen/chickentest/lib"
install: cannot change owner and permissions of '/home/ckellerm/ckeen/lib': 
Operation not permitted
[...]

I don't know if that really is a global problem at all. I have never
noticed this on my systems. Which OS are you running? Would it be
possible for you to set the -g option in your sudo config?

Kind regards,

Christian
