The problem of compiling omp in Rosetta 3.4

When I execute the command:
./scons.py -j? extras=omp bin mode=dubug
I get the following error:
build/src/release/linux/2.6/64/x86/gcc/4.3/omp/libprotocols_a.2.so: undefined reference to `boost::this_thread::disable_interruption::disable_interruption()’

collect2: ld returned 1 exit status
scons: *** [build/src/release/linux/2.6/64/x86/gcc/4.3/omp/FloppyTail.omp.linuxgccrelease] Error 1

Therefore I made the following efforts:
1)I have compiled a new libboost(boost_1_51_0) ， which gain libboost_thread-mt.o/a.
2)Adding the following to the tools/build/basic.settings file
import os
settings = {
“base” : {
“overrides” : {
“CCFLAGS” : “”,
“CXXFLAGS” : “”,
“program_path” : [
“/bin”,
“/usr/bin”,
“/usr/local/bin”,
],
“include_path” : [
“external/boost_1_51_0/include/boost”,
“#external/dbio”,
“/usr/include”,
“/usr/local/include”,
],
“library_path” : [
“/usr/lib”,
“/usr/local/lib”,
“external/boost_1_51_0/lib”,
],
},
},

the same linux ,and in gcc
“CCFLAGS” : ‘-isystem external/boost_1_51_0/include/boost’,
“CXXFLAGS” : ‘-isystem external/boost_1_51_0/include/boost’,

Any guidence on resolving this issue would be greatly appreaciated.
Thanks!
