I'm going to package reticulate https://github.com/rstudio/reticulate
this package has RDEPEND="dev-lang/python"
it will install python files in
/usr/lib64/R/site-library/reticulate/python/rpytools

usptream says:

By default, reticulate uses the version of Python found on your PATH (i.e.
Sys.which("python")).

The use_python() function enables you to specify an alternate version, for
example:

library(reticulate)
use_python("/usr/local/bin/python")


I'm unsure on which python eclass should be inherited

python-r1.eclass if you want to support multiple PYTHON_COMAPT, 
python-single-r1.eclass for using one single PYTHON_COMPAT instead. The 
eclass sets some environment variables (PYTHON,EPYTHON) for you which 
should make the build system use the enabled python version. If the 
upstream build system doesn't do anything too unusual it should just 
work, provided you set appropriate 
python_{prepare,configure,compile,install} phases.
