There is no development packages for bzip2 on SLES 10. It appears to be in the basic system:

On SLES 11
<pre>
# rpm -ql bzip2 | grep lib
# rpm -ql libbz2-devel | grep lib
/usr/include/bzlib.h
/usr/lib64/libbz2.a
/usr/lib64/libbz2.so
</pre>

On SLES 10:
<pre>
# rpm -ql bzip2 | grep lib
/lib64/libbz2.so.1
/lib64/libbz2.so.1.0.0
/usr/include/bzlib.h
