I am trying to establish a connection to oracle through ruby-oci8 with  
the intent on using ActiveRecord.

I have Oracle instant-client installed in the usual system location.

I have these gems installed in my user space:  
activerecord (2.3.2)  
activerecord-oracle\_enhanced-adapter (1.2.0)  
activesupport (2.3.2)  
dbi (0.4.1)  
deprecated (2.0.1)  
fastercsv (1.4.0)  
gnuplot (2.2)  
rake (0.8.4)  
ruby-oci8 (2.0.1)

When I try to require ‘ruby-oci8’, I see this odd error:

irb(main):001:0\> require ‘oci8’  
LoadError: /usr/lib/oracle/10.2.0.4/client64/lib/libnnz10.so: cannot  
restore segment prot after reloc: Permission denied - /home/iono/

from /home/iono/lib/ruby/rubygems/custom\_require.rb:36:in  
`require’

Any ideas?
