I built the same package the old fashioned way (./configure; make;
make install) without any difficulty, and it talks fine to my APC
Back-UPS ES 500. I found apcupsd functional but annoyingly chatty,

when my AC compressor cycles.
I had to apply the following patch to uhid.c to force the device to
attach as "ugen" rather than "uhid":
