title: clsql connect oracle database
body: <p>I am doing some practice with <code>clsql</code>. I want to connect my oracle server hence my connection function is;</p>
  
  <p><code>(connect '("192.168.2.3" "xe" "username" "password") :database-type :oracle)</code></p>
  
  <p>when i hit the return, the following error message shows up.</p>
  
  <p><code>Couldn't load foreign libraries "libclntsh", "oci". (searched *FOREIGN-LIBRARY-SEARCH-PATHS*)
     [Condition of type SIMPLE-ERROR]</code></p>
  
  <p>I have already installed <code>oracle-instantclient11.2-basic-11.2.0.1.0-1.i386.rpm</code></p>
  
  <p>and define <code>export LD_LIBRARY_PATH=/usr/lib/oracle/11.2/client/lib</code></p>
  
  <p>So, what else should I do to connect the server?</p>
