What is the solution to the below?

~/Downloads -> R CMD INSTALL RGtk2_2.20.34.tar.gz
During startup - Warning messages:
1: Setting LC_TIME failed, using "C"
2: Setting LC_MESSAGES failed, using "C"
3: Setting LC_MONETARY failed, using "C"

configure: error: GTK version 2.8.0 required
ERROR: configuration failed for package ‘RGtk2’
* removing ‘/usr/local/lib/R/3.5/site-library/RGtk2’

As directed the version of GTK I manage to install is 2.24.32_2. But for RGtk2 it needs 2.8.0? Could you elaborate on the exact steps to perform to achieve this please?

As I just pointed out in a comment under @zhiyzuo's post (https://zhiyzuo.github.io/installation-rattle/#comment-3944233914), the whole thing can be simplified to this:

system('brew install gtk+')

local({
  if (Sys.info()[['sysname']] != 'Darwin') return()

  .Platform$pkgType = 'mac.binary.el-capitan'
  unlockBinding('.Platform', baseenv())
  assign('.Platform', .Platform, 'package:base')
  lockBinding('.Platform', baseenv())

  options(
    pkgType = 'both', install.packages.compile.from.source = 'always',
    repos = 'https://macos.rbind.org'
  )
})

install.packages(c('RGtk2', 'cairoDevice', 'rattle'))

No more struggling with editing the gtk+ formula :)

I am getting this when doing "R CMD INSTALL RGtk2_2.20.33.tar.gz"

configure: error: GTK version 2.8.0 required

I am on MacOS Sierra 10.12.6, R version is 3.4.2
When I did "brew install --build-from-source --verbose gtk+" it installed GTK 2.24.31_1

I encountered same problem. Did you solve it?
