The i2c and lm-sensors Makefiles use "gcc" as compiler, disregarding the system set CC variable. This means on systems running distcc across different architectures, the resulting .o files will be of incompatible architectures (if they even build), because these require that the compiler be fully specified (e.g. i686-pc-linux-gnu-gcc instead of only gcc). Reproducible: Sometimes Steps to Reproduce: Reproducing is easy, although results can vary depending on numerous race conditions which determine what gets built on what host and what architecture. Simply need a setup with different architectures running distcc. In my case this was a Pentium II 400 running Gentoo, a PowerMac G3 366 running Gentoo/PPC, and an Athlon 800 running Windows 98 SE. Emerging on such a setup with distcc and make jobs set to spread the work around will almost certainly fail in the ebuilds' current state. Actual Results: i2c resulted in incompatible architecture .o files getting installed as kernel modules. lm-sensors build failed when "-mcpu=pentium2" was used as a compile option (unrecognized by the PowerMac's gcc). Expected Results: Both packages set the compiler with the CC variable in their Makefiles. Calling make with CC=${CC} as a parameter, or patching the CC variable in their Makefiles to the right value, would make sure the right compiler is used. Included are patches to the two ebuilds to fix this bug.

Created attachment 24404 [details, diff] fix to i2c ebuild Note that CC needs to also be specified in the install phase as i2c compiles additional material during install.
Created attachment 24405 [details, diff] fix to lm-sensors ebuild
Fixed in CVS; should be in rsync within an hour. Thanks!
looks good, thanks for the quick response
This was resolved quite a while ago. Time for full closure.
