Droid font not available

I downloaded and installed the DroidSans fonts from the 'fonts and templates' ZIP file on the main site.
However when I open the schematic template in InkScape, the text items have 'DroidSans' as the font, with a red line through it. When I look at my fonts list i find 'Droid Sans' (note the space between the words). If I select that font, FZ complains about it when I open the part there. Has anyone run across this and is there a fix? I searched for a 'DroidSans' font without the space and could not find one. BTW - the .ttf file in the ZIP did not have the space.

Thanks, Mike
