As summary says, builds of lm_sensors-2*, or at least the ones currently in the tree (2.10.7 and 2.10.8), fail. The compiler wants to access the kernel headers in /usr/src/linux/include, but it's denied permission. Example: etc/config.c:10:27: error: /usr/src/linux/include/linux/version.h: Permission denied Disabling those features causes the build to succeed. lm_sensors-3.0.2 builds fine with them set.

Please post the output of the command umask run as root. Furthermore, which kernel-sources are you using? Do you use some ebuild to install the kernel-sources or do you install them manually?
