What exactly do you mean when you says "update the pkg tools"?

That (mis)behavior has always been there.

r151014(~/ws/illumos-omnios)[0]% uname -a
SunOS r151014 5.11 omnios-280c743 i86pc i386 i86pc
r151014(~/ws/illumos-omnios)[0]%

Correct also.  isainfo & isalist are the proper illumos interfaces for figuring these things out.

Also correct -- the binaries in /sbin are compiled 32-bit for ancient reasons.  And you may also notice that a binary in /usr/{bin,sbin} is also 32-bit, but there are /usr/{bin,sbin}/{i86,i386,amd64} versions, which are auto-switched-into the correct version based on isainfo:

r151014(~/ws/illumos-omnios)[0]% ls -lt /usr/sbin/dtrace
-r-xr-xr-x  77 root     bin        12768 Feb  3  2015 /usr/sbin/dtrace*
r151014(~/ws/illumos-omnios)[0]% ls -lt /usr/sbin/*/dtrace
-r-xr-xr-x   1 root     bin        57920 Dec 31 01:50 /usr/sbin/amd64/dtrace*
-r-xr-xr-x   1 root     bin        50924 Dec 31 01:50 /usr/sbin/i86/dtrace*
r151014(~/ws/illumos-omnios)[0]% 


As I said earlier, I'm not sure what you mean by "update the pkg tools".  Please elaborate.

Thanks,
