At the source code level, a 64-bit version of libsmi is "libsmi compiled with the compiler generating 64-bit code"; I had no problem building libsmi 64-bit on my machine:

	$ ./wireshark -v
	wireshark 1.5.0 (SVN Rev 33472 from /trunk)

	Running on Darwin 10.4.0 (Mac OS 10.6.4), with libpcap version 1.0.0, with libz
	1.2.3, GnuTLS 2.6.0, Gcrypt 1.4.5.

	Built using gcc 4.2.1 (Apple Inc. build 5659).

I don't know why the 64-bit OS X buildbot build isn't built with libsmi.  I can't speak for the Windows build.  The packages available for various Linux distributions might be build with libsmi, even in the 64-bit versions.

And, of course, if you don't care about SNMP (beyond what the SNMP dissector will get you without libsmi; the dissector exists even without libsmi, it just doesn't interpret variable bindings beyond what you can get by looking at the BER encoding) - which Maverick might not - that might not be an issue.
