how to build gifsicle for x64 Linux

Start an amazon linux 64 bit x86 ec2 AMI (x86 64 bit is super important, that ensures we're on the same platform that lambda runs on.)

login to the ec2 instance and run this:

sudo yum update
sudo yum install autoconf intltool
sudo yum groupinstall "Development Tools"

wget https://github.com/kohler/gifsicle/archive/v1.93.tar.gz

tar -xzf v1.93.tar.gz
cd gifsicle-1.93

autoreconf -i
./configure --disable-gifview
make

then logout and run:

scp -i sp-tmp.pem [email protected]:/home/ec2-user/gifsicle-1.93/src/gifsicle /Users/username/gifsicle/vendor/linux/64/gifsicle

These instructions assume your ec2 instance is running at 18.233.161.219.
