Did you install the perquisite?

$ sudo apt-get install graphicsmagick # Ubuntu
$ brew install graphicsmagick         # Mac OS X

The installation should fail if lwip fails to be installed.

Addressed in https://github.com/IonicaBizau/lwip2/pull/16.

The reason for the error was: in case gm is not available, lwip is installed (and compiled). In case the required tools for compilation are missing (e.g. XCode or so), lwip installation was failing silently. Now that error should block the image-to-ascii installation. 💥
