I was curious what it takes to track down the errors preventing ITK 5.2.1 from being updated on conda-forge?

Thoughts?

So really I am just confused as to the various differences between “itk” and “libitk” and “libitk-devel”?
and the different versions between them?

Hello @imikejackson,
The conda forge [“itk”](https://github.com/conda-forge/itk-feedstock) package and feedstock provide the itk python package for conda. My understanding is that it is a repackage of the PyPi ITK binaries.
The conda forge feedstock [“libitk”](https://github.com/conda-forge/libitk-feedstock) provides the conda forge “libitk” and “libitk-devel” packages. This feed stock build’s ITK from source code. It produces two packages: “libitk” which is the runtime components, and “libitk” which are the development components needed to compile using ITK. The simpleitk feed stocks use these ITK packages on conda-forge.
Hope that help!
