Yes, but install just moves files, it does not *build* anything.

What, I think, is happening is: bz2 module is based on bz2module.c.The
.c module requires header bzlib.h which is not on the include path --
this header does not come with python distribution, it is part of bzip2
distribution. As a result, bz2 module was not built and autodetecting
script setup.py did not add it as extension. From the script:

        # Gustavo Niemeyer's bz2 module.
        if (self.compiler.find_library_file(lib_dirs, 'bz2')):
            exts.append( Extension('bz2', ['bz2module.c'],
                                   libraries = ['bz2']) )

I'll check this theory on Monday by putting bzlib.h on the include path
(cannot log onto testdrive machine now). If configure still does not
add bz2module.c to the makefile, I'll try to add it to Modules/Setup.

Thanks for the help,
  Boris
