Oddity assigning to a hash

my $que = DBM::Deep->new( $path );
%$que = ( ... )
would work.
The errors and code are shown below.
Q: Anything obvious I'm doing wrong?
What the code below gives me is:
USE_DBM=1 perl -Mblib t/14-tied-queue-nofork.t
Skip blib/lib/Parallel/Depend/Util.pm (unchanged)
Skip blib/lib/Parallel/Depend.pm (unchanged)
Manifying blib/man3/Parallel::Depend.3
1..32
Can't call method "free" on an undefined value at /opt/perl/5.10.0/lib/site_perl/5.10.0/DBM/Deep/Engine.pm line 1550.
# Looks like your test exited with 9 before it could output anything.
eyeballing this in the debugger gives me a similar error:
