Thanks for the hints.  Specifically, this is the link I looked at:

http://ruby-doc.org/stdlib/libdoc/net/http/rdoc/classes/Net/HTTP.html

To demonstrate that I can get the proxy to work, I picked google as a
simple example.  Here's what I can do with
elinks and with the http_proxy environment variable set:

$ elinks -source http://www.google.com | wc
     2     173    5212

With ruby this code works:

$ ruby -r'net/http' -e '
proxy_addr = "www-gw32" ;
proxy_port = 3128 ;
res=Net::HTTP::Proxy(proxy_addr, proxy_port).start("www.google.com") {|http|
 http.get("/");
}
puts res.body ;
' | wc
     3     173    5213

While I understand that example (mostly), I don't understand how to
wrap that around my existing code.  Outside of the proxy, this works
just fine:

ruby -rbio -e 'reg = Bio::Registry.new'

When I'm behind the proxy, how can I tell Bio::Registry to use the
proxy connection?
