[boost] Linker error with lambda and VC7.1

I'm using lambda in my project and I'm getting the following linker errors:

stdafx.obj : error LNK2005: "class lambda_functor<struct
boost::lambda::placeholder<1> >::boost::lambda_functor<struct
boost::lambda::placeholder<1> > const & const boost::lambda::`anonymous
namespace'::_1"
(?_1@?A0x2ef08265_at_lambda@boost@@3ABV?$lambda_functor_at_U?$placeholder@$00_at_lamb
da_at_boost@@@23_at_B) already defined in Alloc.obj

stdafx.obj : warning LNK4006: "class lambda_functor<struct
boost::lambda::placeholder<1> >::boost::lambda_functor<struct
boost::lambda::placeholder<1> > const & const boost::lambda::`anonymous
namespace'::_1"
(?_1@?A0x2ef08265_at_lambda@boost@@3ABV?$lambda_functor_at_U?$placeholder@$00_at_lamb
da_at_boost@@@23_at_B) already defined in Alloc.obj; second definition ignored

Although I'm using this lambda::_1 in other places cpp's, the linker
complains only with this use inside Alloc.cpp. What can be causing this?

This is the way I use lambda in Alloc.cpp:

using namespace boost;
using namespace std;
for_each(m_vpData.begin(), m_vpData.end(),
lambda::bind(lambda::delete_ptr(), lambda::_1))
(m_vpData's type is std::vector<unsigned long *>)

Thanks,

PS: i should have posted this message in boost-users, but although I'm
subscribed to that list, my messages are being rejected. I'm trying to fix
this.
