| Interesting problem.  One way to workaround this startup issue with:
| 
|   PKG_LIBS = `$(R_HOME)/bin/Rscript -e "Rcpp:::LdFlags()"`
| 
| used by minqa:src/Makevars
| (https://r-forge.r-project.org/scm/viewvc.php/pkg/minqa/src/Makevars?view=markup&root=optimizer),

Nothing like 'Read the source, Luke!' :)

The *real* problem here is that command has been *obsolete* since early 2014
or for almost five years -- Rcpp does NOT require linking!

Hence the command is a null-op now, provided for backwards-compatibility:

     R> Rcpp:::LdFlags()
     R> 

Then again minqa has not been updated since 2014 either so there...
