Could not verify LLVM version and clang not found

Trying to build jsmess, and latest version of emscripten-fastcomp doesn't support ./configure. I could guess the version I'm using does not have clang in its build. Any advice?

Something went wrong with the install - I'd try to install from scratch, and see if the emsdk says any errors when installing.

Turns out the jsmess repository is now defunt. None of this was necessary.
Anyway I reinstalled from scratch, making I had all of the same versions of emscripten, emscripen-fastcomp, and emscripten-fastcomp-clang, and it worked. Thanks for the help!

Cool, glad things worked out!
