We will be compiling and installing all the packages into
/usr/local. You may want to verify if this folder already exists and its contents before proceeding. The folder
/usr/local does not exist on a fresh installation of Mac OS X.
Create the necessary folders —
sudo mkdir -p /usr/local/src
Modify the ownership of
/usr/local and its children to make yourself the owner.
sudo chown -R $LOGNAME:staff /usr/local
