curlでエラーになってるみたい

curl　を　brew　でインストール

% brew install curl
==> Downloading https://homebrew.bintray.com/bottles/curl-7.49.0.yosemite.bottle.tar.gz

==> Caveats
This formula is keg-only, which means it was not symlinked into /usr/local.

OS X already provides this software and installing another version in
parallel can cause all kinds of trouble.

Generally there are no consequences of this for you. If you build your
own software and it requires this formula, you'll need to add to your
build variables:

    LDFLAGS:  -L/usr/local/opt/curl/lib
    CPPFLAGS: -I/usr/local/opt/curl/include

==> Summary
🍺  /usr/local/Cellar/curl/7.49.0: 364 files, 2.5M
