But if Ref::Util is only recommended, how can compilation of Specio fail because it's missing?

update

that's the error's source

    my $has_ref_util
        = eval { require Ref::Util; Ref::Util->VERSION('0.112'); 1 };

... strange ...

update

OK miracle solved, my colleagues installed a $SIG{'__DIE__'} handler without caring about calls inside eval{...} . This logged a "false" error, which was meant to be ignored.

See $^S for details.
