OK, this works on my Mac:

BEGIN {
    unless ($^O eq 'MacOS') {
        unless (eval "use DBI") {
            warn "Couldn't load module DBI\n";
        }
    }
}

It doesn't try to load DBI and the syntax checking works. (Actually I've
installed DBI on the Mac at work but not yet at home, so...)

The above code looks like the examples in the Cookbook (p. 403)

but on the Unix box I see

   Couldn't load module DBI

even though it actually seems to be loading.

I assume I've missed something obvious / done something stupid :-)
But I don't see it. Please tell me what it is so I can say "Duh". :-/
