Comment 3 for bug 644642

The gist of the missing comment ... continued ...

mongo is happy with the Google V8 JS engine (I have yet to see other usages).

The Apple JS offering I have never seen on linux.

There's lots of interesting applications with "server side JS" _BUT_
they are all grabbing some copy of -ljs and diverging. Proper -ljs
packaging MUST start with
    1) assumption of multiple libraries installed on seperate paths.
    2) additional naming because Mozilla (at least) isn't bothering
    with the usual soname API/ABI conventions.
    3) splitting out the internalized goop (like pcre in mongo, and -lffi in Mozilla)
    so that the packaging starts to be properly engineered.
