The Ubuntu package libbz2-1.0 contains the actual _shared library_ that
programs can use.

However, if you want to _compile_ a program so it can use libbz2, you
need the Ubuntu package libbz2-dev.

Your system almost certainly already contains libbz2-1.0 but before you
can compile gnupg2 so it can use it, you still need the package
libbz2-dev. You should use that one and not bzip2-1.0.6.tar.gz because
otherwise you are installing multiple versions of a shared library and
this should only be done if you understand the implications. Otherwise,
you could cause any program compiled against libbz2 to fail. Although I
think this is unlikely in the case of libbz2 because it only has libc as
dependency. You still might accidentally override a security update
released by Ubuntu, though.

The meat of the Ubuntu packages is as follows:



(That final .so in -dev is a symlink to the .so in libbz2-1.0).
