[R-sig-Fedora] rpmbuild generates dependency on /usr/bin/r

[Jeroen Ooms]

I am trying to create an rpm package for opencpu. The rpm package
compiles and installs a few R packages during build. When Rcpp is
included, rpmbuild automatically generates a dependency on /usr/bin/r,
however there is no such file. Trying to install the packages gives
this error:

  Error: Package: opencpu-lib-1.4.3.99-24.1.x86_64
    Requires: /usr/bin/r

It seems like the R-core and R-devel packages do not contain any
/usr/bin/r file. Why does rpmbuild generate this dependency? Here is a
build log: http://www.stat.ucla.edu/~jeroen/files/log.txt
