My plan is for the JS backend to be sufficiently complete to compile the standard Gambit runtime system.  Because it is not there yet, currently, you have to write your own versions of some of the standard runtime library functions (append, member, etc).

Actually, I should have asked if you did a "make from-scratch" (which is the new way to bootstrap Gambit from the github repo).  So you should be doing:

% git clone https://github.com/feeley/gambit.git
% make -j8 from-scratch

Once this is done, you will have a current Gambit to test things out with.
