I thought I'd follow-up on this (unanswered) query in case anyone else runs 
into similar problems. To summarize, I'd seen two errors with my original, 
cross-compiled agent: 1) related to IPv6 operation, and 2) related to an 
'ia_addr' subcontainer error. 

The IPv6 issue (unrecognized r[ow]communit6 configuration parameters and 
inability to listen on IPv6 endpoints when specified in the configuration file) 
was related to a *stale agent\mibgroup\mibII\vacm_conf.o file*. This was a 
consequence of not running a proper clean (make distclean) prior to 
re-configuring with "--enable-ipv6". Once this was properly re-configured the 
two associated errors were eliminated.

The 'ia_addr' issue appears to be a legitimate issue with the agent when there 
are multiple interfaces defined with overlapping network configurations; i.e., 
both interfaces define addresses on the same subnet. This is easily 
reproducible in such a configuration. The offending agent locale can be seen 
when running the agent with "-DALL" and this points to an issue with the 
'ipAddrTable' implementation. BTW, this error appears to be present in both 
5.7.2.1 and 5.7.3.
