More attempt at making aspell relocatable

Try the trick from
https://groups.google.com/a/continuum.io/d/msg/conda/8yZ3rxED2lk/fOph23UtlRcJ. You

prefix (it won't be installable into a prefix shorter than the one it is built
with).
Add aspell-en package
Don't echo lines to the terminal in the post-link for aspell
