[R-sig-Geo] rPython installation problem

[Javier Martínez López]

Hello all,

I need to combine R and Python to process large raster files and I  
would like to use the "rPython" library for direct transformation of  
the data objects created using those environments. However, when I try  
to install it, it produces the following error related to the python  
libraries (see below). I just installed the Anaconda python  
distribution locally (no admin rights) in my home folder (Linux  
CentOS), which might be causing the problem, but I do not know how to  
deal with this issue, so any help is welcome!

Thank you very much and cheers,

Javier
