Gnuplot first attempt to install on old office iMac using homebrew

I couldn't figure out how to install the required command line tools, and finally found this: (http://stackoverflow.com/questions/20833542/installing-command-line-tools-xcode-5)

Using xcode-select --install in Terminal and choose install tools

(I was asked if I wanted to install command line tools.  Seemed to install fine.)

First attempt to install gnuplot with homebrew:

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

OS X provides the BSD libedit library, which shadows libreadline.
In order to prevent conflicts when programs look for libreadline we are
defaulting this GNU Readline installation to keg-only.

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/readline/lib
    CPPFLAGS: -I/usr/local/opt/readline/include

This formula is keg-only, so it was not symlinked into /usr/local.

OS X provides the BSD gettext library and some software gets confused if both are in the library path.

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

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

Some formulae require a newer version of libffi.

brew update said already up-to-date.

Since Canopy files were in my path, I did as Dr suggested change path:  echo export PATH='/usr/local/bin:$PATH' >> ~/.bash_profile

This didn't get rid of the brew Dr recommendation.

Getting all kinds of clang crap upon install.  Did not build.  Maybe try before canopy install for new computer.
