Yes, that does seem to be the problem with Ruby (on or off of rails). 
Like mod_perl, finding low-cost hosting is difficult because the Apache 
module is too powerful to be safely deployed on a shared server.  Ruby 
on rails *can* be run in CGI mode, but even the developers admit the 
performance is somewhat unbearable running that way.

A "virtual private server" may be useful to you, where you have root 
control over a simulated Linux or FreeBSD instance that's really running 
as one of many instances on a (presumably very powerful) shared machine. 
Interland offers these: http://www.interland.com/vps/ and another 
provider that comes highly recommended (though I have no direct 
experience with them) is John Companies which offers both Linux and 
FreeBSD-based VPS servers: http://johncompanies.com/

These days though, with the prices of dedicated servers from EV1, 
Rackspace, ServerMatrix, and their ilk falling fairly steadily, I'm not 
sure if a *real* dedicated machine is much more expensive than a virtual 
one anymore...

Either way, though, you assume the responsibility of installing, 
configuring, managing and monitoring your mod_whatever-enabled Apache 
(and everything else running on the box) when you rent a dedicated 
server, so that affects the cost, features and value in your decision as 
well, especially for a potentially high-traffic site.

hth!
