DIST= error wrongly suggests DISTRO=

Using prevu for first time so I'm still learning. I successfully backported gnucash from gutsy against Feisty. (I"m running feisty.) I'm running the version of prevu that installs from synaptic under feisty -- version 1:0.4.1bzr46-0ubuntu2

I wanted to try backporting to Edgy so I entered

  DIST=edgy sudo prevu gnucash

The script halted and told me it wasn't ready for edgy, It told me I needed to type this first:

  DISTRO=edgy sudo prevu-init

I followed its suggestion, and it initialized FEISTY again.

CORRECTION -- line 51 of /usr/bin/prevu

if not os.path.exists('/var/cache/prevu/%s.tgz' % self.target_distro): raise NoBuildEnvironment("Not ready to build for %s. You need to run 'DISTRO=%s sudo prevu-init'." % (self.target_distro, self.target_distro))

should be changed to

if not os.path.exists('/var/cache/prevu/%s.tgz' % self.target_distro): raise NoBuildEnvironment("Not ready to build for %s. You need to run 'DIST=%s sudo prevu-init'." % (self.target_distro, self.target_distro))
