[Clas_offline] scons trouble

[Johann Goetz]

Hi Puneet,
Yes, the problem looks like the PYTHONPATH environment variable is not set
to the right place. It should have this path in it:
    /group/clas/builds/64bit/STABLE
FYI, this is where the "build_system" is located. In the the build_system
directory are several python scripts which make up the interface used to
build clas software with SCons.

This is probably a result of the environment64.csh file not being correct.
Keep in mind that if the build_system directory is not found, python will
look for it in the current working directory, so making a symbolic link to
the build_system directory where you want to compile your code is equivalent
to setting the PYTHONPATH variable.
