BOINC is failing to use Mac's resolver libraries and fails to properly implement IPv6 resolver internally.

My Setup:
Mac OSX 10.6.6
BOINC 6.12.11 or 6.10.58
DNS resolvers: IPv6 2001:470:882a::1 and 2001:470:20::2

BOINC reports unable to connect to internet:

Don't know about the BOINC code, but BOINCstats/BAM! does not yet have IPv6 support (the whole data center doesn't have it).

Please do not PM, IM or email me for support (they will go unread/ignored). Use the forum for support.

At this point, I am not overly concerned that the BOINC data center is not IPv6 enabled. The trouble is on the local computer. The only IPv6 communication I am attempting is between my computer and my DNS resolver. Applications should be using calls to the OS to look up DNS, and if done so, this would succeed. Instead, BOINC uses its own resolver and it does not understand the IPv6 resolvers I have installed in my /etc/resolv.conf file and thus, any DNS name look-ups fail.

It has been so long that I have been using BAM and BOINCstats, that I failed to realize, until just now, that BOINC is a project out of Berkeley. Reporting over there.
