oci8 problems

 I feel stupid having to ask this, but I haven't found an answer.  I installed ruby-oci8 in order to load data from an oracle db into postgres (part of a jsp to rails conversion).  In order to run my ruby script I know I need to set ORACLE_HOME and LD_LIBRARY_PATH environment variables to get it to work (and it does work).

I've tried setting ENV['ORACLE_HOME'] and ENV['LD_LIBRARY_PATH'] in config/envrironment.rb (before the Rails::Initializer.run do |config|  line), but this doesn't fix the issue.  I don't know where to set it so mongrel will pick it up.

By the way, I'm not even trying to use the oracle active record adapter with rails.  I just have oci8 installed for the migration script.

Please help.

Thanks in advance,
andy
