Installing WGET for MAC OS X Lion (and others)

First, use curl to download the latest wget source:
curl -O http://ftp.gnu.org/gnu/wget/wget-1.13.4.tar.gz

Next we use tar to uncompress the files you just downloaded:
tar -xzf wget-1.13.4.tar.gz

Use cd to change to the directory:
cd wget-1.13.4

Configure with the appropriate –with-ssl flag to prevent a “GNUTLS not available” error:
./configure --with-ssl=openssl

Build the source:
make

Install wget, it ends up in /usr/local/bin/:
sudo make install

Confirm everything worked by running wget:
wget --help

Clean up by removing wget source files when finished:
cd .. && rm -rf wget*

You’re all set, enjoy wget in Mac OS X.
