If you’re going through the Beyond Linux From Scratch guide, and run into this error while compiling qca-2.0.3 (and I assume many other versions of qca), I think I can help.
You don’t seem to have ‘make’ or ‘gmake’ in your PATH.
The fix is relatively easy. Just make sure to have which installed on the machine. Jake found this out the hard way by looking through the configure script. Doing this experiment on Linux From Scratch has really given me an appreciation for distributions that come with basic utilities such as which.
Since which is very difficult to find on Google, here is a link: http://www.linuxfromscratch.org/blfs/view/svn/general/which.html
