 Upgrading Boost from 1.49.0_0 to 1.50.0_0 fails to build - Shell output:
 {{{
 --->  Building boost
 Error: org.macports.build for port boost returned: command execution

 Please see the log file for port boost for details:
 /opt/local/var/macports/logs/_opt_local_var_macports_sources_rsync.macports.org_release_ports_devel_boost/boost/main.log
 Error: Unable to upgrade port: 1
 }}}
 The full log file is attached. This is rather lengthy but the key problem
 seems to be multiple occurrences of: 'Undefined symbol:
 "___sync_fetch_and_add_4"'

 The system I am using is:
 System: MacBookPro1,1 (Processor: Intel Core Duo (32-bit mode only)[[BR]]
 OS: MacosX 10.6.8 [[BR]]
 XCode: Version 3.2.6
