[Rd] Check package issue on mavericks

[Gionata Bocci]

Dear List,

  I've realized that the "CRAN Checking Package" system returns some
Warnings for my package TR8 under "r-release-osx-x86_64-mavericks"; all the
warnings include the following message "Invalid MIT-MAGIC-COOKIE-1 key"
which I find a little cryptic.
  After some web searches, I understood that "MIT-MAGIC-COOKIE" is related
to the X server and most of the messages reporting issues with that are
related to R packages having problems with "mavericks" (either NOTES or
Warnings resulting from the "checking process").
  Not having a Mac available where I could try to explore this issue (and
not being familiar with Mac in general), I've set up a Travis CI account in
order to check whether the package was built and "checked --as-cran" on
both Linux (my OS) and Mac OSX (Travis is using OS X versions >= 10.10): it
looks like everything is fine, correctly built and checked.
  I am thus writing to ask if other developers on the list have found and
fixed this issue (so that I could fix that as well and tick the checkbox "I
have fixed all problems shown on the package check page" before submitting
a new version to CRAN).
  Best,


Gionata.
