make: *** [Makefile:19: main] Error 1

What am I doing wrong?

is the pre-built binary set up to use the newer shifted keys? If so, then I won't have to build the hex file.

What version of Ubuntu/SDCC are you using to build? On Ubuntu 18.04LTS with SDCC 3.5.0 doing "make clean" and then "make" gives a binary 12,212 bytes in size, which is a bit tight (but still 1K free). I think newer versions of SDCC might be less efficient at code generation. If you do want to build it, SDCC has few dependencies, so I think it is possible to install older versions of the package. Other compilers (e.g. Keil) are probably even more efficient, but I don't have a license for the 8051, and also it's not free.
