Looks like an interesting project - one day, I'd like to explore the various 
machine learning toolkits. I notice they've recently switched to a cmake-based 
build system, so you may be better off experimenting with the development 
version.

Those checksum errors have since been fixed - it's usually a sign of a 
corrupted download, but some projects think it's a good idea to re-release a 
package without incrementing version numbers.

If you haven't made any other changes:

git checkout -- .
git pull

will undo your local changes and bring you up to date.

Github pull requests are the preferred option.

That will take a long time to build all of mxe, it may be better to start with 
just the packages you need:

make blas eigen hdf5 lapack ...

You can also run:

make update-checksum-cfitsio

To re-download the package and fix these kind of errors (if you're sure it's 
not an actual download issue)
