Ok, here you go:

dom3 -Tv
Dominions 3, version 3.06 (Jan 28 2007 15:13:01)'

/usr/local/games/dominions3/dom3_x86 -Tv
Dominions 3, version 3.06 (Jan 28 2007 15:13:01)

which dom3
/usr/local/bin/dom3

ls -l /usr/local/bin/dom3
lrwxrwxrwx 1 root staff 32 Oct 4 17:52 /usr/local/bin/dom3 -> /usr/local/games/dominions3/dom3*

ls -l /usr/local/games/dominions3/dom3
lrwxrwxrwx 1 root thejeff 8 Oct 4 17:52 /usr/local/games/dominions3/dom3 -> dom3_x86*

And for which library it's actually using:
ldd `which dom3` | grep libc
libc.so.6 => /lib/tls/libc.so.6 (0xb7c82000)

ls -l /lib/tls/libc.so.6
lrwxrwxrwx 1 root root 13 Feb 5 05:51 /lib/tls/libc.so.6 -> libc-2.3.6.so

I can't think of anything else to check. Everything indicates I'm running 3.06 using libc-2.3.6.
I don't know why it's working.
