Not my experience. The .travis.yml I use for random (still) installs curl from source, yet is done in under a minute. I never remember whether others can browse my test history but try https://travis-ci.org/eddelbuettel/random/builds As Michael Rutter has curl in his cran2deb4ubuntu PPA knows by the R-Travis setup, I might as well install his r-cran-curl which would make this yet a little faster. | Let me mention again that this problem is not specific to my package or | quantmod.

Use of curl (to provide https) will become much more common. R now supports it in R 3.2.0, but only as optional build-time choice. With that I find Jeroen's package a pretty good choice. But that is of course just one suggestion, and if it doesn't work for you I fully understand. I was faced with the exact same problem -- Mads switched random.org to https-only -- and would like to see what other suggestions people may have.
