thanks martin for your 'finger'to pthreadvc.lib. libs seem to be ok now.
however it's like this mythical dragon, you ax off 1 head and get back two:
LINK : fatal error LNK1181: cannot open input file 'Files\pd\bin;\msvc\Build;\win32_vcpp\Build;\objs /DLL /MANIFEST /MANIFESTFILE:d:\Gem-do-2\build\win-vs2008\Debug\Gem.dll.intermediate.manifest /MANIFESTUAC:level='asInvoker'.obj'
my building environment not right?
