Thanks for the pointers! The `run-webkit-archive` script included in the ZIP file helped, too.

I now use a script of the following form to invoke the `jsc` binary:

    $ cat "$(which jsc)"
    #!/usr/bin/env bash
    DYLD_FRAMEWORK_PATH=/path/to/download/Release DYLD_LIBRARY_PATH=DYLD_FRAMEWORK_PATH=/path/to/download/Release /path/to/download/Release/jsc "$@"
