Ok... mate-applets package builds and installs now, but looks like the real problem is that the cpufreq applet is being linked to the versioned library (instead of libcpupower.so or libcpupower.so.1).
$ ldd /usr/lib/mate-applets/mate-cpufreq-applet | grep cpupower libcpupower.so.4.13.0-32 => /usr/lib/libcpupower.so.4.13.0-32 (0x00007f04df4a6000)
In Debian it looks better:
$ ldd /usr/lib/mate-applets/mate-cpufreq-applet | grep cpupower libcpupower.so.1 => /usr/lib/libcpupower.so.1 (0x00007f5e94357000)
