My box has a 2.6.9-55.0.6.EL kernel, but Centos only wants to give me a  
1.8.1 ruby, and yum doesn’t see an eruby. Yum did get an erb, but it  
looks to me like that is old hat. Can I just treat the erb as eruby and  
put it in my cgi-bin (the directions for eruby install in my pickaxe  
says put it in the cgi-bin)? Or even better, does someone know an RPM  
that is known to work? I googled a link for a Fedora core one, but I  
would like one that is known to go well on this Centos. I pulled down  
the tar.gz file thing from a site and it is complaining when I run the  
configure.rb file that there are missing headers (presumably mkmf.rb).

I took your suggestion. CentOS has Ruby 1.8.5, NOT 1.8.6, but that’s  
still an improvement. It also has eruby, as you said. I haven’t tried  
it out yet, but it’s there. One thing I wonder, however, is how I add  
things like hpricot or an XML parser, as ruby-gems is not there, and  
these things are supposed to be installed with yummy package managers,  
which appear to be incomplete for Ruby stuff…?
