No mistake, I just did not have enough information as to which version you
wanted to be compatible with ;-) So to be compatible with the ones built into
the 1.30.2 bin-stage you would need to use the single threaded versions.
Single threading was, and still is, the default build configuration which is
the only version that BPL builds to the bin-stage in 1.30.2. You can see that
(which is what I did as I did not know until now ;-) by looking at the long
build path...
"./bin/libboost_python.so/gcc/release/runtime-link-dynamic/shared-linkable-true"
is the *single threaded* version. If that had a threading-multi subdir it
would be the multi threaded version.

So you want the ones without the "-mt" indicator in the new build.

Also you should read the "install? and simple thread program." thread as it
has some additional points on using BPL as it comes out of the build system.
