What is that x11-misc/read-edid good for? I do not want to pull
the whole x11 stuff with it, as this is a server with no graphics.

lm_sensors-2.10.3.ebuild: Add missing depend.
decode-edid.pl needs parse-edid from x11-misc/read-edid

I agree with the original poster of this "resolved" bug:
pulling in x11-stuff to server just to be able to monitor
its temperatures is simply dangerous and risky...
Next, I want to use sensord for monitoring, so I modified
package.use and tried it once more:

# echo "sys-apps/lm_sensors sensord" >> /etc/portage/package.use
# emerge --pretend lm_sensors

emerge: there are no ebuilds built with USE flags to satisfy
">=x11-libs/cairo-1.4.6[svg]".
!!! One of the following packages is required to complete your request:
- x11-libs/cairo-1.8.6-r1 (Change USE: +svg)
(dependency required by "net-analyzer/rrdtool-1.3.8" [ebuild])
(dependency required by "sys-apps/lm_sensors-2.10.7" [ebuild])
(dependency required by "lm_sensors" [argument])

Now I do not understand it at all. Why rrdtool? All I want
to use sensord for is to have some status messages recorded
to syslog. Why should I install that x11-libs/cairo graphics
library and rrdtool stuff???
Likely sensord does a lot more than recording to syslog.
man sensord:
DESCRIPTION
Sensord is a daemon that can be used to periodically log
sensor readings from hardware health-monitoring chips to
syslog(3) ***OR*** a round-robin database (RRD) and to alert
when a sensor alarm is signalled; for example, if a fan fails,
a temperature limit is exceeded, etc.
You see that big fat ***OR*** there? syslog or RRD. And I think
even gentoo-user should have the right to choose what he wants
to do with those sensor-readings. Definitelly I'm against any
x11-libs on my server, be it x11-misc/read-edid or x11-libs/cairo.
BTW, sensord can write data to round-robin database even if no
rrd-tool is installed. There's no need to put net-analyzer/rrdtool
as a dependency...
