What version of OS X is this?
Ah. I've upgraded to Snow Leopard. It turns out that in Snow Leopard tar is
bsdtar which is a change from Leopard which had tar = gnutar. But
/usr/bin/gnutar still exists so I guess we should just have configure pick that
one. I'm a bit surprised that I'm the first one to trip over this, Manuel has
been validating on Snow Leopard for quite some time now. Manuel, doesn't this
happen for you?
I am rarely validating on my laptop, but usually use our Xserve (which is much
faster), which still runs Leopard. I guess that is why I didn't tip over it.
Do we really have to rely on a specific version of tar? Dependencies like that
always come back to bite you.
It sounds like the --force-local option is required iff tar is GNU tar.
So we should have a configure test for that.
Cheers,
Simon
