Hi, it looks like that log is from a release build, could you try doing 
a debug build? I haven't tried doing a release build on my local copy 
before. There might be some preprocessor definitions that I forgot to 
copy from the debug to release configuration.

I had a quick look at my local copy, and the release build is missing 
some preprocessor definitions, try adding these:

I think the 'inconsistent dll linkage' errors are because 
'MAPNIK_EXPORTS' isn't defined.

The other projects will also need to be checked to make sure they have 
the proper release settings.

If this doesn't work, I'll try to get some time at the weekend to get 
the visual studio build working on svn trunk.

I hope this helps,
