How do I add missing dictionaries for aspell?

If you've installed pspell/aspell via a package channel, the dictionaries may be available in another package. On CentOS 6 using default yum repositories, English dictionaries are in package aspell-en.

I had same problem on Fedora 22. I solved it by installing aspell-en.x86_64package.

Download dictionaries from here: Unzip it and do,

    make install

All the instructions are in README. This Makefile will find the correct locations that these dictionaries should go to.
