Re: [boost] Help compiling Boost needed please

The 1.27.0 release presented various problems with building the Python
library. So
many fixes for the process have been made since then that I can't
recommend 1.27.0 anymore. I suggest you try the version in the CVS:
https://sourceforge.net/cvs/?group_id=7586

By the way, bpl_static is not used anymore (even in 1.27.0);
Boost.Python now lives in a dynamic library.

Thanks,
Dave
