Common Brew install messages

Even after insalling a package dont mean its available for the system if its keg-only its not linked as the system have already a version. If you whant to build with that lib or package you must include the LDFLAGS  and CPFLAGS in your make file or you can try to –force linking for your compile .


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
