Installation issue

[bwanab]

Ubuntu 20.04, emacs 27.1, supercollider 3.10

After installing, using cmake to build the *.el files, when I do m-x sclang-mode on a buffer I'm getting:

defconst: Symbol's function definition is void: sclang-make-buffer-name

I'm willing to debug, but I'm hoping somebody has some clues to what the problem might be.

Me too, here is the backtrace:

Does M-x sclang-start give similar errors?
