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. <b>But first you need to add a custom path to libbz2 in 
this line[1357] in setup.py<b>:

# 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)
