I have some orthophoto files (Erdas Imagine format) enclosed in a vrt file. When I view it in any desktop GIS it has proper RGB colors, but when I use the vrt in Mapnik to render some tiles, I get grayscale images as a result. Why?

Update: If I convert the Erdas Imagine files into png-s (I need transparency where there is no data) Mapnik render works ok, so I guess it's something to do with how Mapnik interprets Erdas files and its bands.
