Errors installing "dplyr" in r

Question

Question: unable to install dplyr in R... code below. Anyone offer any solutions? I'm on a mac osx sierra and R Version 1.0.136

> install.packages("dplyr")

  There is a binary version available but the source version
  is later:
      binary source needs_compilation
dplyr  0.5.0  0.7.0              TRUE

Do you want to install from sources the package which needs compilation?

The downloaded source packages are in

> library(dplyr)
Error: package or namespace load failed for ‘dplyr’ in loadNamespace(i, c(lib.loc, .libPaths()), versionCheck = vI[[i]]):

Not sure why this isn't working! Tried to download manually and it didn't work either (similar/same warnings/errors)

A new dplyr version was accepted into CRAN yesterday. Usually CRAN provides packages for both Windows and OSX in binary form, but it takes up to 48 hours for CRAN to provide the compiled packages.

When you try to install a package in that time window, R asks you to either install the previous binary version or the new version from source. If you decide to install the version from source you will need to have a c++ compiler.

The easiest thing for you to do is to either install the previous binary package or wait until the latest version gets compiled at CRAN.

Checkout https://cran.r-project.org/web/packages/dplyr/index.html to see if the binaries for your OS are already available.

Update: It seems there are some issues with the latest dplyr version, and the OSX compilation seems to fail. More info here: https://cran.r-project.org/web/checks/check_results_dplyr.html. I would rather stay with 0.5.0 until those issues are ironed out.
