brew doctorをすると
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/libecomlodr.dylib
Warning: You have unlinked kegs in your Cellar
Leaving kegs unlinked can lead to build-trouble and cause brews that depend on
those kegs to fail to run properly once built. Run `brew link` on these:
autoconf
ruby-build
tmux

のこいつは
rm /usr/local/lib/libecomlodr.dylib
で解決
参考：Homebrewのlibecomlodr.dylibがいらないというWarningを修正する。
二つ目
Warning: You have unlinked kegs in your Cellar
Leaving kegs unlinked can lead to build-trouble and cause brews that depend on
those kegs to fail to run properly once built. Run `brew link` on these:
autoconf
ruby-build
tmux
$ brew link tmux
Linking /usr/local/Cellar/tmux/2.0... 4 symlinks created
$brew link tmux
で
tmuxを有効にするそうです。
でOK
もともとtmuxが使えなく困っていたので
よかった。
他の ruby-build と autoconf も同じ要領。
