linux - virtualenv yolk 呼び出しの python3 が IOError を引き起こす

Question

ubuntu lucidでは、デフォルトでpython 2.6.5コンパイルpython3.3.1してセットアップしvirtualenv、wrapperworkon envpy331でpython3.3.1で作業できるようにしました。次に、使用してyolkをインストールしましたpip

今、私が走るとき

>>yolk -l

以下のように python2.6.5 でもインストールされているすべての python ライブラリを一覧表示し、最後に IOError をスローします

BeautifulSoup   - 3.0.7a       - active development (/usr/local/lib/python2.6/dist-packages)

    f = open(self.path,'rU')
IOError: [Errno 2] No such file or directory: '/usr/lib/python2.6/dist-packages/onboard-0.0.0.egg-info'

なぜこれが起こるのか分かりますか？python3 を再度コンパイルして virtualenv をセットアップする必要がありますか?
