When I try to install Rhtslib on my Macbook running Mac OS 10.13.4 High Sierra, I get the following compilation error:

ERROR: compilation failed for package ‘Rhtslib’

Unfortunately, there isn't any suggestion in the error message about how to resolve the error, and I can't find anyone else who has a similar error via Google searching. So can someone suggest how I might fix this error and get Rhtslib installed?

Well, by chance, I happened to run brew upgrade today, and among other things, it upgraded R from 3.4.x to 3.5.0, and Rhstlib installed just fine on 3.5.0. So chalk this one up to just another ghost in the machine, I guess.
