The blfs book mentions a sed command which is not verified yet:

sed -e 's/"(\\S+)"/"?([^\\s"]+)"?/' -i scripts/update-leap/update-leap.in

Configure the package:

./configure --prefix=/qlnx \
            --without-sntp \
            --mandir=/qlnx/man \
            --sbindir=/qlnx/bin \
            --libexecdir=/qlnx/bin/libexec \
            --datarootdir=/tmp \
            --enable-ipv6

–sbindir=/qlnx/bin, –libexecdir=/qlnx/bin/libexec
    The installer creates these empty directories, thus we have to define the correct location.

–without-sntp
    Disable the simple network protocol (snmp)

–datarootdir=/tmp
    Prevent installing unwanted documentation and share data.

–enable-ipv6
    Not sure if this is necessary, but it does no harm if not.

Build and install ntp:

make
make install

Remove a deprecated tool and obsolete man page:

rm -v /qlnx/bin/ntpdc
