>Description:
As of pkgsrc-HEAD, leading to pkgsrc-2018Q1, "sysutils/apcupsd" still
uses "devel/libusb" directly instead of using the
"mk/libusb.buildlink3.mk" framework (and thus the "libusb-compat"
shim to allow libusb-0.x users to use libusb1).

libusb-0.x and libusb-compat conflict so apcupsd can't coexist with
other packages which have converted to use the libusb-compat shim.

While simply changing the relevant buildlink3.mk inclusion allows
apcupsd to build, the resulting binary seems to send out repeated
"connection restored" messages on the monitoring host (but not to
apcupsd slaves on the network).

So, more investigation is needed.
>How-To-Repeat:
See above.
