Error installing R package Rmpfr - Error in rematchDefinition

I'm running RStudio 1.1.419 on linux mint, and trying to install the CRAN package Rmpfr for arbitrary precision number support.

As per other questions I've installed:

sudo apt-get install libmpfr-dev

Then I've restarted RStudio, and tried installing the Rmpfr package again. The installation fails with the following error which I don't see on stack overflow or google.

** preparing package for lazy loading
Creating a generic function for ‘factorial’ from package ‘base’ in package ‘Rmpfr’
Creating a generic function for ‘quantile’ from package ‘stats’ in package ‘Rmpfr’
Creating a generic function for ‘mean’ from package ‘base’ in package ‘Rmpfr’
Creating a generic function for ‘median’ from package ‘stats’ in package ‘Rmpfr’
Error in rematchDefinition(definition, fdef, mnames, fnames, signature) :

That's a nifty one.

stats::median has changed - you are still using R 3.2, in which case:

> stats::median
function (x, na.rm = FALSE) 
UseMethod("median")
<bytecode: 0x0000000008473270>
<environment: namespace:stats>

Whereas now, we have:

> stats::median
function (x, na.rm = FALSE, ...) 
UseMethod("median")
<bytecode: 0x000000001071c050>
<environment: namespace:stats>

Rmpfr has been updated recently, see here for reference:
https://r-forge.r-project.org/scm/viewvc.php/pkg/R/Summary.R?view=markup&revision=272&root=rmpfr

You should upgrade R if you want to use the latest version of Rmpfr.
