I copied the installation from teh preproduction to the production,
and got the same error, so it's not from a difference in compilation,
but a difference in the environment, either OS, libraries or hardware.
But I have no idea what. Any ideas welcome.

New adventures in Varnish: Turns out the machines have wildly
differing Linux versions. 2.6.17.6 vs 2.4.31. Could that be the
difference? 2.4... that's pretty old.

Varnish is designed for FreeBSD 6 and Linux 2.6. It will not work
properly with Linux 2.4.

OK, that's what I though. Thanks for the confirmation.

Varnish does not support Linux 2.4.

It might work, but we will never check if it does. The reason is that
Varnish uses "modern" OS features. That's the reason it performs so
well :)

Looks like 2.4 doesn't have a monotonic clock. We should check for
that in configure.ac...

We can fall back to CLOCK_REALTIME in that case, but we suffer ill
effects if the clock is stepped (by NTPD or otherwise).

And how necessary is it to support Linux 2.4 in the first place?
Failing when you run ./configure seems to be a good option to me.
