[lldb-dev] Python3 compatibility for the API

Right, the existing version that is built and what you are using links
directly against a 2.7 libpython at compile time.  So you would probably
need to build LLDB from source and tweak the build system to make it
possible to link against your 3.x version of python.  There's some build
instructions on the website <http://lldb.llvm.org/build.html>.  I know
there's a few linux developers around here, so it's possible someone else
would be interested in making this work as well, but I don't know that it's
on anyone's immediate timeline.

In any case, if you want to try it yourself, the first step would be to get
a working build (even with 2.7), and once you have that working we can look
at how to make it link against Python 3.
