I’m using Ubuntu, and have never heard of dash (though I just checked and verified that /bin/sh is a symlink to it). Are you saying that, if no shebang is given, the build step ignores the SHELL variable and runs /bin/sh –ex? This would explain much.

Exactly what is being run without a shebang? What sh is, depends on your OS. It may be bash, or something else.
