Description of problem:
The spacewalk-utils package contains a spacewalk-export tool. Spacewalk-export tool uses the spacewalk-report tool contained in spacewalk-reports package. Spacewalk-utils package doesn't have dependency on spacewalk-reports and the spacewalk-export tool fails with traceback without spacewalk-report tool installed.

How reproducible:
Always

Steps to Reproduce:
1. Install the spacewalk-utils package
2. Make sure the spacewalk-reports package is not installed
3. Run spacewalk-export

Actual results:

Traceback

[root@hostname]# spacewalk-export
INFO: Processing users...
Traceback (most recent call last):

    globals()[entity.lower().replace('-','') + 'Dump'](options)

    _issueReport(options, 'users')
  File "/usr/bin/spacewalk-export", line 163, in _issueReport
    stdout = open(report_file, 'w'))

  File "/usr/lib64/python2.7/subprocess.py", line 1327, in _execute_child
    raise child_exception
OSError: [Errno 2] No such file or directory

Expected results:
Spacewalk-export should create the export archive. It should either have spacewalk-report installed as a dependency or at least show some reasonable error message about missing spacewalk-reports package.
