Thanks peter. 1. Does it say anywhere that the build process should use src/Makevars? I'm not sure, where should it say that? I'm using the default options in Rstudio to create a package
2. Also notice that an important part of the package concept is that packages can be distributed. The package that i want to build uses MPI. Is that a problem? My understanding is that in order to use MPI i have to set FC to mpif90. Is that wrong? 3. build configuration belongs in the build environment I'm not sure if I follow. What is the correct way of telling Rstudio that the package i'm building uses MPI? Thanks again!
