Fedora 12 maxes out it’s Ruby version at 1.8.6. Unfortunately, compass / sass requires 1.8.7. The following steps creates a suitable RPM, and installs it :

# cd ~
# wget http://mo.morsi.org/blog/files/ruby-
# yum install rpm-build
# yum install ncurses-devel gdbm-devel tcl-devel tk-devel libX11-devel  autoconf db4-devel byacc bison emacs compat-readline5-devel
# rpmbuild --rebuild ruby- 
# cd /root/rpmbuild/RPMS/i386/
# rpm -Uvh *

$ export RUBYLIB="/usr/lib/ruby/site_ruby/1.8/:/usr/lib/ruby/1.8/"
$ compass create XYZ
