[Visualpython-users] non standard install of vpython-4.beta16

[Jaap S. <j....@hc...>]

I tried to install Visual with the python version coming with SAGE:
http://www.sagemath.org/


"make install" fails to make an executable vpython:
1) there is still a ${prefix} in the file vpython
2) IDLE points to the wrong place

But running vpython then fails:

No problems with libboost_python when I install visual-4.beta16 with my standard python2.5
What is going on here?
