Thanks Kevin,

apt-get install irb didn’t work, but it got me thinking. apt-get had  
installed ruby 1.8.4 minus irb. I installed 1.8.5 from scratch and this  
had irb, but it turns out was missing yaml and zlib, whic I apt-got  
(correct tense?). Of course this installed them under /usr not  
/usr/local so I had to copy them. Seems to be working, but I must do  
some cleanup later or I will confuse the hell out of myself.

If you installed 1.8.5 from source and didn’t have yaml something bad  
probably happened.

If you installed 1.8.5 from scratch and zlib wasn’t built you  
probably were missing the zlib libraries on your system.

You shouldn’t be copying these files across ruby versions. It may  
lead to strange bugs.
