Homebrewを使って、rbenvをインストールしようと試みたところエラーが発生し、
terminal
$ brew doctor
で確認したところ、以下のようなWarningが出現したので、その解決方法を備忘録として残しておきます。
Please note that these warnings are just used to help the Homebrew maintainers
with debugging if you file an issue. If everything you use Homebrew for is
working fine: please don't worry or file an issue; just ignore this. Thanks!

解決法
まずは上のWarningから。（下のWarningも解決方法同じでした！！）
Warning: Unbrewed dylibs were found in /usr/local/lib.
If you didn't put them there on purpose they could cause problems when
building Homebrew formulae, and may need to be deleted.
Unexpected dylibs:
/usr/local/lib/libgvplugin_core.6.dylib
/usr/local/lib/libgvplugin_dot_layout.6.dylib
/usr/local/lib/libgvplugin_gd.6.dylib
/usr/local/lib/libgvplugin_neato_layout.6.dylib
/usr/local/lib/libgvplugin_quartz.6.dylib
①ターミナルに以下を入力します。（ファイルの作成）
terminal
$ vim ~/.del_files.sh
②〜が並んだページが出現するので、１行目に#!/bin/bashを貼り付け、２行目以降にUnexpected dylibs:に記載されているファイルをコピペします。(以下、参考)
terminal
#!/bin/bash
/usr/local/lib/libgvplugin_core.6.dylib
/usr/local/lib/libgvplugin_dot_layout.6.dylib
/usr/local/lib/libgvplugin_gd.6.dylib
/usr/local/lib/libgvplugin_neato_layout.6.dylib
/usr/local/lib/libgvplugin_quartz.6.dylib
③カーソルを一番上のファイル（２行目）の頭におき、ctrl + vで矩形選択のビジュアルモード（VISUAL BLOCK）に移行。↓カーソルで一番下のファイルの頭まで選択し、:を押します。
すると、下のラインに既に :'<,'>が入力された状態でコマンドラインが表示されるので、続けて s/^/rm -f /と入力します。（rm は、ファイルやディレクトリを削除してあげるコマンドで、 -f は、「削除しますか？」的なメッセージを都度出さないようにするオプションです。）
④Enterを押して、全ての行（一番上以外）の先頭にs/^/rm -f /が追加されているのを確認したら、もう一度:を押します。一番下の行に入力欄が出てくるので、wq!と入力し、Enterを押します。
⑤通常の入力モードに戻るので、そこで
terminal
$ bash ~/.del_files.sh
を実行。これでファイルが削除されます。
⑥以上が完了したら、
terminal
$ brew doctor
を実行し、エラー文が消えていたら、成功です。
追記
⑦もし、以下のようなWarningが出現した場合
Warning: Broken symlinks were found. Remove them with `brew cleanup`:
/usr/local/lib/libgvplugin_core.dylib
/usr/local/lib/libgvplugin_dot_layout.dylib
/usr/local/lib/libgvplugin_gd.dylib
/usr/local/lib/libgvplugin_neato_layout.dylib
/usr/local/lib/libgvplugin_quartz.dylib
エラー文に従って、
terminal
$ brew cleanup
してあげましょう。
こちらのWarningも上記と同じ方法で解決できます！！
