所以我在Win7上用conda构建了一个包：
conda skeleton pypi $pkgname
conda build $pkgname
binstar upload ./conda-bld/win-64/$pkgname-py27_0.tar.bz2
conda install -c https://conda.binstar.org/myname $pkgname
使用 python2k，这就像一个魅力。但是，使用 python3k 会失败，因为该patch包不适用于 python3k。错误（例如docopt）：
$ conda skeleton pypi docopt
Using url https://pypi.python.org/packages/source/d/docopt/docopt-0.6.2.tar.gz (25 KB) for docopt.

python3k没有patch包 - 这是否意味着我没有包构建？
