PS.  I noted I have a few matches for 'ruby'.  Not sure if this is
significant re my problem

# find / -name ruby
/usr/local/bin/ruby
/usr/local/lib/ruby
/usr/bin/ruby
/usr/lib/swig1.3/ruby
/usr/lib/ruby
/root/source/redmine-0.7/vendor/plugins/coderay-0.7.6.227/lib/coderay/scanners/ruby

# which ruby
/usr/local/bin/ruby
