[vtkusers] Error building VTK on OSX 10.1

[Chris]

Hi

Trying to build VTK on OSX Quartz, I've "hidden" my usr/X11 directory
and changed the CMakeCache.txt with BUILD_SHARED_LIBS:BOOL=ON
but I still get the following cryptic error msg:

ld: Undefined symbols:
__ZNSt8ios_base4InitC4Ev
/usr/bin/libtool: internal link edit command failed
make[3]: *** [/Develop/osxBin/bin/libvtkCommon.dylib] Error 1
make[2]: *** [default_target] Error 2
make[1]: *** [default_target_Common] Error 2
make: *** [default_target] Error 2

I really don't know what's wrong.  Anybody got suggestions??
