I cannot reproduce this -- how did you identify that a DNS lookup
happened? Straceing the binary doesn't reveal any lookups when I do:
strace -s200 -f make check TESTS=gs2-krb5 2>&1 |grep -e '[^0-9a-f]53[^0-9a-f]'
-e josefsson
So I'm not sure the problem actually is a DNS lookup, it could be
something else. I have tried removing /etc/shishi, ~/.shishi and
/etc/resolv.conf, without any difference.
It would be great to see this resolved, to make the build robot start to
produce real builds.
Thanks,
