Pedro,

That is correct, the Mapnik binaries provided for windows do not  
include the gdal plugin with support for formats such as ecw or MrSid.

You would need to recompile the library that is the 'gdal  
plugin' (with is separate from Mapnik's core library) against a gdal  
version built with that support.
