"GNU Make not found. Try setting the environment variable GNUMAKE."

I am trying开发者_JAVA百科 to install Steel Bank Common Lisp as described in this article.

However, when I do this step:

sh-3.2# INSTALL_ROOT=/usr/local sh install.sh

I get this error:

GNU Make not found. Try setting the environment variable GNUMAKE.

How, exactly, do I install GNU Make and set the environment variable GNUMAKE on Mac OS X?

Install the Developer Tools that came on a DVD ROM with the machine. GNU make is included in XCode (version 3.81 on my Leopard box).

If you don't have the ROM, you can sign up as a developer (for free) and download a disk image.

To install GNUMAKE:

# pkgin install gmake
