python - How can I use conda to install pydot?

Question

Trying to generate some PDF's of decision trees by following some of the sklearn documentation, but can't get Pydot on my machine. Is there any way to use the conda installer to install the pydot package? Based on the command line errors I'm seeing, it may be a 64bit issue. I use binstar search to find the package channel:

C:instar search -t conda 

Which gives the recommendation of looking at the packages in detail using

binstar show j14r/pydot

Which then tells me to

conda install --channel https://conda.binstar.org/j14r pydot

But when I run the conda install command, I get the following error (same error for all the pydot packages listed):

Fetching package metadata: ...
Error: No Packages found in current win-64 channels matching: pydot
You can search for this package with 

binstar search t conda pydot

which sends me back to the beginning of this all. Any ideas? Thanks all.
