In a sense, but what I really wanted was /usr/ports/audo/p5-CDDB_get
(which my tree didn't have until I started tracking HEAD about an hour
ago). And, after some careful checking I've found what has been
causing my problems.

I'll file a more specific bugrep in a bit, but shortly:
/usr/libdata/perl5/site_perl/i386-openbsd/sys/cdio.ph calls _IOR for
CDIOREADTOCHEADER with "struct ioc_read_toc_header" for the t (type)
parameter. It does not seem likely that _IOR's sizeof call is
returning the proper value (4) to pass onto _IOC. It appears that the
%sizeof array is not being generated as a global symbol, at least on
my OpenBSD install. It looks like I can get around this by putting
specific sizeof defines in cdio.ph, but is there a more preferred way
to do this?
