Please send __complete constructions__.  It is not clear what you ran here
but I believe you wanted

    R CMD INSTALL --build myPackageName_1.0.0.tar.gz

or

    R CMD INSTALL --build .

to create the .zip file.  Else just use

    R CMD INSTALL .

to install directly without a zipfile. 

I just did the last one on my machine win7 / 64 bit machine at work.  [ Where
for reasons I do not fully understand I had to add "-std=c++0x" for the 64
bit build CXXFLAGS but not the 32 bit build). ]

It works for me (TM).

When 'R CMD check' is running on Rcpp (eg at CRAN) this is executed too and
tends to work.  So chances are your setup is not correct, or you didn't
follow the instructions to the letter.

R development using compiled source code is (in my mind) much more difficult
on Windows as the setup is both very manual and finicky. If you can work on
Linux, I recommend that you do. If you can't follow the instructions closely.
