Maybe distcc is being invoked during the configuration steps shown in that
log, with the output redirected somewhere else.

This is the content of /var/tmp/portage/.distcc/lock/ after the build:

When distcc tries to distribute work to a particular host, and that fails,
distcc temporarily marks that host as "bad", and will not try distributing
any work to that host for the next 1 minute.  This is to avoid the
possibility of further overloading a host that is already overloaded.

Still any ideas what could be wrong?


We still don't have enough information.
Try running the build, then when it fails either wait one minute, or do the
rm commands that you did before,

   rm -rf /root/.distcc
   rm -rf /var/tmp/portage/.distcc

(but do NOT remove all the temporary build directories)
and then try the build again - hopefully the second time around, it won't
re-run the configuration steps.

Alternatively, if that still doesn't work, try removing those two .distcc
directories, and then running just the distcc command, e.g. (from your log
file)

distcc i686-pc-linux-gnu-g++ -D_BSD_SOURCE -D_XOPEN_SOURCE=500 -D_BSD_SOURCE
