Lore assumes pyenv is installed in a specific way

[thomasfulton]

Specifically it assumes it is NOT installed through brew, but manually installed by cloning the git repo. If you try to run lore install with pyenv installed this way you get

> lore install                                                                                                                                                                                   
WARNING pyenv executable is not present at /Users/thomasfulton/.pyenv/bin/pyenv
Would you like to blow away ~/.pyenv and rebuild from scratch? [Y/n] n
ERROR please fix pyenv before continuing

If you symlink your pyenv executable to that location you eventually get
