Great to hear it finally compiles! Could you please check whether this
is still a problem also in CMake 2.4.6 ? If so I would report the
problem together with some other smaller issues we've hit previously.
In that case I will also check in a workaround for this problem - it
seems that all *BSD platforms are affected.

I think adding the section below to root CMakeLists.txt should solve
the problem without the need to specify -pthread explicitly. Could you
try it?

IF (CMAKE_SYSTEM_NAME MATCHES "BSD")
  SET (CMAKE_SHARED_LINKER_FLAGS ${CMAKE_SHARED_LINKER_FLAGS} -pthread)
  SET (CMAKE_EXE_LINKER_FLAGS    ${CMAKE_EXE_LINKER_FLAGS}    -pthread)
  SET (CMAKE_MODULE_LINKER_FLAGS ${CMAKE_MODULE_LINKER_FLAGS} -pthread)
ENDIF (CMAKE_SYSTEM_NAME MATCHES "BSD")
