The error message is telling you that the code has been linked against boost 1.42. This happens sometimes when either boost or cmake is a bit overly clever. If you're using a recent version of cmake (at least 2.8.3), the easiest way to fix this is to add "-D Boost_NO_SYSTEM_PATHS=ON" to your cmake command along with the -D BOOST_ROOT that you are using. An example command, from the bottom of that wiki page, is: cmake -D BOOST_ROOT=/usr/local -D Boost_NO_SYSTEM_PATHS=ON .. Note that it's probably best to start from scratch (remove the contents of your build directory) before doing this. Once you have built the code, you can quickly test if that worked by doing: ldd $RDBASE/rdkit/rdBase.so Check the output of that and see which version of the boost python library it's using. -greg ------------------------------------------------------------------------------ Better than sec?
