I don't know the answer to this...but did you try removing your domain
entry from your resolv.conf file to see if that made a difference (so that
there are only nameserver lines and a search line)? On my system, those
two don't work too well together. In the man page, it says they are
mutually exclusive, but then I read from someone else that they aren't on
linux. In any case, having only a search line works for me.

The real nslookup is part of the 'bind' package.

Not being a bash user, I don't know the answer to this. If spaces between
parens shouldn't matter, then it is a bug...
Note that /bin/bash -c '( (xli foo.gif); echo bar) &' *does* work!
Since this is hardcoded, the other thing you could do as a kluge is to
remove the inner parens as well and replace them with spaces.
