Can you let us know what the Depends: are?

I think this is not a problem with your build. It seems like you try to load
another package _which itself needs a rebuild_.   Could be as simple has
having to rebuild RcppArmadillo.

We did make a chance in 0.10.1 which required all packages using Rcpp to be
reinstalled.  We try to keep such changes to a minimum, but sometimes you
gotta do what you gotta do...

| 
| One other difference between the compilation runs:
| 
| These are in my package:
| basics.cpp
| calc_anclikes_sp.cpp
| rcpp_hello_world.cpp
| rcpp_module.cpp
| 
| But the compilation of these:
| Num.cpp
| stdVector.cpp
| 
| ...is new I think, this didn't happen when I compiled in 
| 2.14 IIRC.

I have no idea what you are trying to day, and please note that your example
is __NOT REPRODUCIBLE__ as we do not have your sources.  Always try to
distill to small reproducible cases.
