This usually happens when compinit is invoked before and after you
modify fpath. The biggest offender here is Ubuntu. Its global zshrc
has this awfulness:

    # If you don't want compinit called here, place the line
    # skip_global_compinit=1
    # in your $ZDOTDIR/.zshenv
    if grep -q '^ID.*=.*ubuntu' /etc/os-release && [[ -z
"$skip_global_compinit" ]]; then
     autoload -U compinit
     compinit
    fi

The solution is to add skip_global_compinit=1 to ~/.zshenv.

Naturally, you also need to ensure that your own rc files invoke
compinit only once, after all changes to fpath.
