DYLD_LIBRARY_PTH issue with Anaconda IPython

[pluskid]

Just to document this issue here in case anybody else might have the same issue. The current Anaconda Python on Mac OS X is eating the DYLD_LIBRARY_PATH environment variable when calling ipython. So import mxnet works in python but does not work in ipython or IPython Notebooks due to CUDA related dependencies not found (libcudart.so etc.).

The issue is documented in conda/conda-build#628, and a current hacky workaround is documented in ipython/ipython#8878
