../js/src/configure --prefix=/usr       \
                    --with-intl-api     \

Now, as the root user: 

make install

Command Explanations

--with-*: These parameters allow the build system to use system versions of the above libriares. These are required for stability.

--enable-readline: This switch enables Readline support in the JS shell.

--disable-jemalloc: This switch disables the internal memory allocator used in JS60. jemalloc causes a conflict with glibc.
