Cluster, any idea how to solve this? As far as I know we do not have a RESTRICT=distcc?

Reporter, please post `emerge --info` from both localhost and the distcc node.

Forgot NEEDINFO.

Looks like a general problem with the kbuild system, then. Thank you for verifying this.
can you please enable distcc debugging and paste the buildlogs please. as far as I know, it isnt a specific issue with kbuild, since it just calls said compiler - possibly some Kbuild vs gentoo oddity?

Also, sorry for the lack of distcc longs on target. The last time I tried to get one, it didn't work, and it's slipped my mind since. I'll try and try again sometime later.
(In reply to comment #13) > Confirmed for util-linux as well... Please open a separate bug report for this as it has nothing to do with linux-mod.eclass.
This shouldn't be difficult to fix, just need to pass emake HOSTCC=$(tc-getBUILD_CC) CC=$(tc-getCC) to tell KBuild the right compilers to use. I actually do that already in alsa-driver.
Diego, that should already be in the current code anyways. Could you also review 133382 as I think this is going to be relevant?
might help you in case you didn't catch it but i think that bug is a dup of http://bugs.gentoo.org/show_bug.cgi?id=167844 because the pentium 3 that cause the trouble is also using an hardened kernel. At least easy to test with same computers with non-hardened kernel
Added RESTRICT="distcc" to linux-mod.eclass w/o realizing it needed special support. Adding dependency bugs.
This exact error has been fixed. You're trying to pass a module through distcc to be built on a hardened host. This wouldn't work before, see bug #167844. Fixed via patch to distcc adding USE="hardened". emerge --sync and rebuild distcc with USE="hardened".
