Is your build trying to use precompiled headers that you generated
before updating boost? If so, they would have references to the
vc90.pdb files. After the PDB update, you'd need to execute a clean
rebuild (deleting the pch files manually if boost's clean does not
remove them), to regenerate PCH files with references to the new PDB
files.

I am not using precompiled headers on my current project and did not
test them with the PDB change I suggested. But they should word -- I'm
certain I've used this PDB scheme with precompiled headers using IDE
project files on a previous project.
