title: gcc unable to find shared library libisl.so
body: <p>I installed gcc version 5.1 locally on a cluster having OS as CentOS where I dont have root access (so i cant use any commands like '<code>sudo</code>'). (The global gcc version installed is 4.4). I also modified the path variable to include the path to my local version at the beginning of the path variable. Before, when I was trying to install boost using the global version, it worked fine. But now, when I try to install boost, it shows the following error:</p>
  
  <pre><code>/users/home/head/cmp/soft/sft/gcc/bin/../libexec/gcc/x86_64-unknown-linux-gnu/5.1.0/cc1: error while loading shared libraries: libisl.so.10: cannot open shared object file: No such file or directory
  </code></pre>
  
  <p>Any ideas on how to fix this will be highly appreciated.</p>
