I tryied to make the msn backend work on windows and I updated the instructions on the readme in emesene.
the new stuff is related to the papyon backend for msn that now is the only supported backend and has some dependencies (OpenSSL, pyCrypto) and those need to be installed.
to make both instructions similar I recommend that you download and install msysgit from here:
http://code.google.com/p/msysgit/
and follow the instructions from here:
http://emesene-msn.blogspot.com/2010/10/instructions-for-testers.html
until you downloaded emesene code and updated the submodules, then follow the instructions in the INSTALL_WINDOWS.txt file here is an updated version:
https://github.com/marianoguerra/emesene/blob/master/INSTALL_WINDOWS.txt
I got emesene to run using papyon with this setup but the portable version gave me protocol error, if you can find the way to fix it it would be great.
still waiting for packages...
EDIT: I forgot to add one instruction, before running python
setup.py py2exe you need to copy the papyon folder that is in emesene/emesene/e3/papylib/papyon/papyon to emesene/emesene/papyon, something like:
cp -r emesene/emesene/e3/papylib/papyon/papyon emesene/emesene/
to avoid the import error trying to load papyon.
