I am trying for the first time to build vpython from sourceforge (I am 
actually trying to make a Fink package for 2.9.4 on MacOSX). Until now I 
had only tried 2.1.9 from vpython.org.

There is now a boost package in Fink, so I had hope this might work 
without too much trouble. Unfortunately, compilation fails with the 
error message below. I don't know enough C++ to see whether this has to 
be fixed in boost or in visualpython, or whether something else needs to 
be done. gcc is the version that comes with OSX 10.3.4 and XCode tools 
1.2,  gcc 3.3 20030304 (Apple Computer, Inc. build 1640). Any advice 
welcome.
