Are you trying to build one of the sample projects? I see this forum post had the same issue a year ago, and says the solution You could correct the sample and offer a pull request:

https://groups.google.com/forum/?fromgroups=#!topic/route-me-map/YajRgFDoN00

I also think the samples work in the Alpstein fork: https://github.com/Alpstein/route-me

It might be a majority of route-me users use Alpstein now.
