I'm trying to follow along this bit from scikit-learn about plotting a decision tree using graphviz.

When I run

(datasci)benjamins-MacBook-Pro-2:Scripts Ben$ dot -Tpdf iris.dot -o iris.pdf

I get the following error message

dyld: Library not loaded: /usr/lib/libltdl.7.dylib
Referenced from: //anaconda/envs/datasci/bin/dot Reason: image not
found Trace/BPT trap: 5

There is definitely a file in my working directory named "iris.dot", so I'm not sure why I'm getting an "image not found" error. Any suggestions?

Specs: Mac OSX 10.11.1, Anaconda virtual environment with graphviz 2.38.0

    The "image not found" message may be referring to `/usr/lib/libltdl.7.dylib` rather than to `iris.dot`. I suggest confirming that the dynamic library exists. If it doesn't there may have been an installation problem. – Simon Dec 21 '15 at 23:29
  • @Simon yep. I eventually found [this post](http://stackoverflow.com/questions/12323252/brew-doctor-dyld-library-not-loaded-error-no-available-formula-for-zlib) which helped me. – Ben Dec 21 '15 at 23:42
