Error relating to the logging package when trying to generate R easyconfigs?

I see the following error when trying to run the script to generate an updated easyconfig for R:

```
Error in as.environment(pos) : using 'as.environment(NULL)' is defunct
Calls: <Anonymous> -> assign
Execution halted
```

This is with the Fedora R RPM on a Fedora 23 system, with Bioconductor installed using BiocLite (to pick up the versions from the 3.2 release).

The R version is 3.2.2.
