Thanks, Jan.  That made gem work.  Complete notes here:

Now on to bio-graphics:

$ sudo apt-get install libpango1-ruby libcairo-ruby

$ sudo gem install bio
Bulk updating Gem source index for: http://gems.rubyforge.org
Successfully installed bio-1.2.1
1 gem installed

$ sudo gem install bio-graphics
Successfully installed bio-graphics-1.4
1 gem installed
Installing ri documentation for bio-graphics-1.4...
Installing RDoc documentation for bio-graphics-1.4...

$ gem list

*** LOCAL GEMS ***

bio (1.2.1)
bio-graphics (1.4)
rubygems-update (1.0.1)

So far so good. But I don't understand the following results:

$ true ; ( set -x
ruby -e "p 'hello'"
ruby -rbio -e "p 'hello'"
ruby -e "require 'bio'; puts 'hello' "
export RUBYOPT=rubygems
ruby -e "require 'bio'; puts 'hello' "
ruby -e "require 'bio'; require 'bio-graphics' ; puts 'hello' "
ruby -rbio -e "p 'hello'"
) >& output.txt

$ cat output.txt
+ ruby -e 'p '\''hello'\'''
"hello"
+ ruby -rbio -e 'p '\''hello'\'''
ruby: no such file to load -- bio (LoadError)
+ ruby -e 'require '\''bio'\''; puts '\''hello'\'' '
-e:1:in `require': no such file to load -- bio (LoadError)
        from -e:1
+ export RUBYOPT=rubygems
+ RUBYOPT=rubygems
+ ruby -e 'require '\''bio'\''; puts '\''hello'\'' '
hello
+ ruby -e 'require '\''bio'\''; require '\''bio-graphics'\'' ; puts
'\''hello'\'' '
hello
+ ruby -rbio -e 'p '\''hello'\'''
ruby: no such file to load -- bio (LoadError)

So, the good new is that it seems as though I now have bio-graphics installed.

Now the question I have is, is  there any reason why the -r option
does not seem to work as expected, i.e. doesn't load the bio library?
