Hello. We are sorry but we cannot help you. This mailing list is to work on developing Python (adding new features to Python itself and fixing bugs); if you're having problems learning, understanding or using Python, please find another forum. Probably python-list/comp.lang.python mailing list/news group is the best place; there are Python developers who participate in it; you may get a faster, and probably more complete, answer there. See http://www.python.org/community/ for other lists/news groups/fora. Thank you for understanding.

Would it be a problem? Depends on what are you going to do. Oleg.

I've faced the same problem: while installing packages packed in .tar.bz2 using pip it failed with the same error on importing BZDecompress from _bz2 module (it could not find the _bz module). So You can solve the problem by adding a prefix with direct location to your compiled python3.3. But first you need to add a custom path to libbz2 in this line[1357] in setup.py:

Gustavo Niemeyer's bz2 module.

if (self.compiler.find_library_file('/lib/i386-linux-gnu/libbz2.so.1.0.4/', 'bz2')): # lib_dirs, 'bz2')):

then make && make -f Makefile-libbz2_so && make install (and be careful passing correct --prefix to ./configure)
