Install on OSX without homebrew

[valeriyvan]

What's the way to install it on OSX without homebrew?
make build fails with:
docker build -t dergachev/screengif .
make: docker: No such file or directory
make: *** [build] Error 1

I haven't tried it, but I suppose you would install the dependencies (XQuartz, ffmpeg ImageMagick, Gifsicle, and pkg-config) however you wish and then build and install the gem from source:

$ gem build screengif.gemspec
$ gem install screengif-<version>.gem

If you look at the Makefile, you'll realize it's only useful for installing and running screengif in docker. To install screengif without homebrew, you'd find some other way to install it's dependencies (I haven't tried, on a mac).

Then just run gem install screengif to install the gem as normal.
