[boost] <build>no in common properties

Hi, The Sandia-darwin-intel-11.0 results are failing because essentially every Boost product is not being built (actually being skipped). This message is present for almost every Boost library. Skipping build of: ../libs/date_time/test/date_time_serialization <build>no in common properties Skipping build of: ../libs/disjoint_sets/disjoint_sets <build>no in common properties Skipping build of: ../libs/dynamic_bitset/dynamic_bitset <build>no in common properties Skipping build of: ../libs/exception/test/is_output_streamable_test <build>no in common properties Any idea what's up with this? The Sandia-leopard-x86 results didn't seem to suffer from this problem last night. Thanks. -- Noel
