first time run on CentOS 5.6 - exception trying to run dpkg-query

Hi there,

I seem to be having a problem with blueprint attempting to run dpkg-query on my CentOS 5.6 box. Is this a bug?

[root@linweb05 ~]# blueprint create linweb05
# [blueprint] searching for PEAR/PECL packages
# [blueprint] searching for Python packages
# [blueprint] searching for apt packages
Traceback (most recent call last):
  File "/usr/bin/blueprint-create", line 5, in <module>
    pkg_resources.run_script('blueprint==3.0.2', 'blueprint-create')
  File "/usr/lib/python2.6/site-packages/pkg_resources.py", line 461, in run_script
    self.require(requires)[0].run_script(script_name, ns)

  File "/usr/lib64/python2.6/subprocess.py", line 1139, in _execute_child
    raise child_exception
OSError: [Errno 2] No such file or directory

I've reproduced this with the latest stable tarball, and with the latest git clone.
