This ebuild is in portage since more than four month and there are no bugs posted against this version. Also there is a change for 2.6.22, see http://www.lm-sensors.org/wiki/Kernel2.6: "In kernel 2.6.22, the way the I2C adapters are presented in sysfs changed, and this affects libsensors. You will need lm_sensors version 2.10.3 or later. Alternatively, the kernel can be compiled with CONFIG_SYSFS_DEPRECATED=y, then version 2.10.2 will work too. Older versions of lm_sensors will complain that the I2C adapter names can't be read. This is only a warning though" So please stabilize at least this version. Reproducible: Always Steps to Reproduce:
With kernel 2.6.22 and lm_sensors 2.10.1 I can't use gnome-sensors-applet maybe because of the problem Arne Stacker said. With ~amd64 version of lm_sensors (2.10.4) it works fine.
