I figured that much, but I can't figure out what it is.  Trying to gain
more insight into that was why I added the gigabit adapter to minbar.

Not enabled in the first place.  /etc/hosts is fine (and almost empty)
on both machines.

Hmm, good call.  Interesting:

minbar:root:/home:130 # ifconfig -a
lo0: flags=2001000849<UP,LOOPBACK,RUNNING,MULTICAST,IPv4,VIRTUAL> mtu
8232 index 1
        inet 127.0.0.1 netmask ff000000
hme0: flags=1000843<UP,BROADCAST,RUNNING,MULTICAST,IPv4> mtu 1500 index 2
        inet 10.24.32.12 netmask ffffff00 broadcast 10.24.32.255
        ether 8:0:20:92:9e:46
e1000g0: flags=201000851<UP,POINTOPOINT,RUNNING,MULTICAST,IPv4,CoS> mtu
1500 index 3
        inet 10.24.34.2 --> 10.24.34.1 netmask ffffffff
        ether 8:0:20:92:9e:46

And that hme0 is remotely pingable.  Yet...

minbar:root:/home:131 # dladm show-dev
hme0            link: unknown   speed: 100   Mbps       duplex: full
e1000g0         link: up        speed: 1000  Mbps       duplex: full

Curious and suspicious.

minbar:root:/home:137 # dladm show-link
hme0            type: legacy    mtu: 1500       device: hme0
e1000g0         type: non-vlan  mtu: 1500       device: e1000g0

minbar:root:/home:146 # svcs -a | grep forward
disabled       11:07:54 svc:/network/ipv4-forwarding:default
disabled       11:07:54 svc:/network/ipv6-forwarding:default

Nope.
