QuickFix: ViewVC ImportError: No module named svn error
Recenlty I was in need to update a old subversion server to latest one in a CentOS 5.2 box. I removed the older rpms and compiled subversion from latest source. Everything seems fine except ViewVC which is used to browse svn repositories.
Following error was occuring:

ImportError: No module named svn
Solution: You need to install python bindings for svn.
Step 1: Check whether SWIG library is installed in your system or not (most distribution already have):
# rpm -qa | grep -i swig
swig-1.3.29-2.el5
Its there in my system, if you doesn’t get any output then install the library by using yum install swig or manually by from here.
Step 2: Install python bindings for SWIG. I assume you have subversion source avaialble with you. Untar the source and you will be able to find the bindings in /usr/src/subversion-1.6.1/subversion/bindings/swig/python directory.
# cd /usr/src/subversion-1.6.1/
# make swig-py
# make check-swig-py ### Perform checks
# make install-swig-py
If you face any issue while this installation, pls check INSTALL file in /usr/src/subversion-1.6.1/subversion/bindings/swig directory to get further instructions, otherwise the library should be installed successfully and programs like ViewVC or other ones which requires swig python bindings should run fine.
