[R] RSPython won't load in R 2.6.0 under Linux

[Prof Brian Ripley]

Please take this up with the RSPython maintainer (current address in the 
CC and in version 0.7-1).

I think you have not built R as a shared library, and that symbol only 
exists when you do (it is not the default).

The same happens in the released R: we will have to wait a couple of 
months to see what happens in 'R 2.6.0'.

Even with R built as a shared library I get

> library(RSPython)
Error in ifelse(R.version$os == "Win32", ";", ":", ) :
   unused argument(s) ()
Error in library(RSPython) : .First.lib failed for 'RSPython'

which is a bug in the package.  (Duncan: that is what .Platform$path.sep 
is for, and on Windows R.version$os is "mingw32" - for 32-bit builds at 
least.)
