Of course. The problem here isn't Viper but it seems that your SWIG
wrapped DOLFIN module (_cpp) has been linked with the wrong Boost library
(libboost_program_options-gcc41-mt-1_38.so.1.38.0).

The versionless symbolic link probably pointed to
libboost_program_options-gcc41-mt-1_38.so.1.38.0 at the time of linking
(when _cpp.so was built). Try to rebuild and reinstall DOLFIN and PyDOLFIN
with your latest Boost version.
