Doh! Use Zip Picker and download and install all of the Zip files suggested. Each zip file should be unzipped into the same base directory like c:\djgpp. Each Zip file overlays the same directories but they unzip different files necessary to install the environment you have chosen. Set the appropriate environment variables (I use a batch file) and you're ready to go.

In most cases this is caused because of not installing the
"Basic assembler, linker" zip package
