Hi I am using Boost 1.39.0 on Sun os. I have compiled boost libraries myself with sun toolset using these options ./bootstrap.sh --with-toolset=sun While building i get this error ./boost/python/detail/wrap_python.hpp", line 78: Error, usererror: #error Python 2.2 or higher is required for this version of Boost.Python i have python 2.4 installed on my machine, and it is in my PATH variable, however boost build is not picking it up. Is there somehow i can explicitly specify in the jam command line. ---- Yogesh
