Do you run virtual hosts on same Apache processes?
If so the ruby interpreter is shared by all virtual hosts.
This may cause problems.

`require' loads same library only once, so /rb/tools.rb will not be loaded.

The error message on my environment (mod_ruby/1.2.4 
Ruby/1.8.2(2004-08-24)) is here:

[Wed Oct 13 01:08:09 2004] [error] mod_ruby: error in ruby
[Wed Oct 13 01:08:09 2004] [error] mod_ruby: ../rb/tools.rb:3:

(I change name_of_host to Foo, name_of_host_subdir to Bar.)
