python and readline

$ python3.6

$ ldd `which python3.6`
/usr/pkg/bin/python3.6:
        -lpython3.6.1.0 => /usr/pkg/lib/libpython3.6.so.1.0
        -lintl.1 => /usr/lib/libintl.so.1
        -lc.12 => /usr/lib/libc.so.12

        -lutil.7 => /usr/lib/libutil.so.7
        -lm.0 => /usr/lib/libm.so.0


Is history / line editing not available in pkgsrc python36 or is it
just me?

Cheers,
