Hi all:

In Ubuntu, I have to install a program into my home directory because I do
not have the privilege to install in the usr/local/bin and usr/local/lib
directory.

~/OT/usr/local/lib/site_ruby/*.so  # many so files
~/OT/usr/local/lib/site_ruby/1.8/
~/OT/usr/local/lib/site_ruby/1.8/x86_64-linux/*.so                  #
 includes many .so files
~/OT/usr/local/lib/site_ruby/1.8/OT.rb
   # load a number of    *.so files located in "x86_64-linux/"
~/OT/usr/local/lib/site_ruby/1.8/OT/RT/RT.rb                              #
RT.rb  has  "  require 'OT'    "

There are load errors in RT.rb  and OT.rb

It works perfectly if I put in the /usr/local directory instead of home but
I do not have the permission.

I have add system search path ~/OT/usr/local/lib/site_ruby/1.8/
and ~/OT/usr/local/lib/site_ruby/1.8/x86_64-linux/ but it still does not
work.

So my question is that how to configure to make the ruby or system search
the lib and .rb files?  I use tcsh.

Thanks,

JH
