Subject: Ruby 1.4.6 - trouble with require path

I inherited a project that uses Ruby 1.4.6 on a RedHat Linux 6.1J. I
copied it onto my RedHat Linux 6.1J machine, but there is a problem
when I try to build it; the ruby scripts are unable to find required
files (located in the same directory as the scripts) when the script
is executed from a different directory. I upgraded to Ruby 1.6.7,
which fixed that problem, but the scripts are not quite compatible
with the updated Ruby, so I had to revert to the version that was
originally used.

As an example, lets say I have two ruby scripts in a directory:
     /scripts/script1.rb:
          #!/usr/bin/ruby
          require "script2"
     
     /scripts/script2.rb:
          print "Testing...\n"
     
     Command Prompt:
     [testing]# cd /scripts
     [scripts]# script1.rb
     Testing...
     [scripts]# cd /testing
     [testing]# script1.rb
     script1.rb:2:in `require': No such file to load -- script2
(LoadError)

With Ruby 1.6.7, it works fine. With Ruby 1.4.6, it can find
script1.rb, but not script2.rb.

There must be a way to correct this, as the project apparently worked
for the original developers. I'm using the same OS, and I added the
same ruby options and script directory to my path as specified in
their readme (well almost, they said put it in .cshrc, but I had to
put it in .tcshrc for it to work):
     setenv RUBYOPT '-Ke -rkconv'
     set path = ( $path /scripts)

I also tried the following:
     setenv RUBYOPT '-Ke -rkconv -S'
     setenv LOAD_PATH /scripts
     setenv RUBYLIB /scripts

So what am I missing here? Does anyone know how I can get this to work
correctly WITHOUT ALTERING THE SCRIPTS (because there are hundreds of
scripts)?
