It turns out that in FreeBSD (possibly also in other BSD-derived
environments), PF_UNSPEC is defined (in /usr/include/sys/socket.h), but
only if "__BSD_VISIBLE" is true:

g1-252(11.0-S)[3] grep -nwC 6 PF_UNSPEC /usr/include/sys/socket.h
323-#include <sys/_sockaddr_storage.h>
324-
325-#if __BSD_VISIBLE
326-/*
327- * Protocol families, same as address families for now.
328- */
329:#define     PF_UNSPEC       AF_UNSPEC
330-#define     PF_LOCAL        AF_LOCAL
331-#define     PF_UNIX         PF_LOCAL        /* backward compatibility */
332-#define     PF_INET         AF_INET
333-#define     PF_IMPLINK      AF_IMPLINK
334-#define     PF_PUP          AF_PUP
335-#define     PF_CHAOS        AF_CHAOS
g1-252(11.0-S)[4] 


And while PF_UNSPEC is referenced in the sources for the R openssl
package, __BSD_VISIBLE is not:

g1-252(11.0-S)[33] dirs
~/R/Rtmp4VjFtY/dhw/openssl 
g1-252(11.0-S)[34] grep -nrw PF_UNSPEC .
./src/ssl.c:41:  hints.ai_family = PF_UNSPEC;
g1-252(11.0-S)[35] grep -nrw __BSD_VISIBLE .
g1-252(11.0-S)[36] 


And it appears that the local sources are ephemeral, so I can't
readily patch those sources to see if I can get it to work (as the
patched sources wouldn't be used) -- unless I miss the mark....

Any suggestions for how I might proceed?

Thanks!

Peace,
david

How could one possibly "respect" a misogynist, racist, bullying con-man??!?
