Recently I run into the problem that a team had a requirement for subversion 1.6.6 (while CentOS 5u3 was not supporting this… but the vendor didn’t provide a newer release). This team also had a requirement to have TRAC… TRAC is depended on Python… but I was not allowed to update the subversion bindings for python by updating the it on the whole system… so… this is what I did:

• Installed a number of devel packages:

     # yum install apr-devel neon{,-devel} apr-util-devel
  

• Compiled sqlite version 3.6.13 and installed it on NFS:

    $ ./configure --prefix=/nfs/apps/webservices/trac-parent/sqlite/3.6.13
  
    ...
  
    $ make ; make install
  
    ...

• Compiled subversion 1.6.6 and installed it on NFS:

  $ make clean; ./configure 
  
   --prefix=/nfs/apps/webservices/trac-parent/subversion/1.6.6 
  
   --with-sqlite=/nfs/apps/webservices/trac-parent/sqlite/3.6.13 
  
   --without-neon 
  
  ...
  
  $ make -j8 ; make install ; make swig-py ; make install-swig-py
  

  …

• Added the following line to /etc/sysconfig/httpd:

  export LD_LIBRARY_PATH=/nfs/apps/webservices/trac-parent/sqlite/3.6.13/lib/
  

• Modified /etc/httpd/conf.d/trac.conf by adding a ‘PythonPath’ to the location-directive:

  <Location /projects>
  
    ...
  
    PythonPath "['/nfs/apps/webservices/trac-parent/subversion/1.6.6/lib/svn-python'] + sys.path"
  
  </Location>
  

• Restart the trac daemon:

  # service httpd stop
  
  # service httpd start
  

• Now you’ve to resync the trac-instance with Subversion (the
  repository_dir value in the trac.ini of the instance).. but make sure
  you use the correct bindings in Python:

  # export LD_LIBRARY_PATH=/nfs/apps/webservices/trac-parent/sqlite/3.6.13/lib/
  
  # export PYTHONPATH=/nfs/apps/webservices/trac-parent/subversion/1.6.6/lib/svn-python
  
  # trac-admin ${TRAC_INSTANCE_PATH} repository resync "*"
