The distribution works with proper dependencies. When R is built with
libcurl, the R package already depends on libcurl:

edd at max:~$ dpkg -s r-base-core | grep curl
Depends: zip, unzip, libpaper-utils, xdg-utils, libblas3 | libblas.so.3, libbz2-1.0, libc6 (>= 2.16), libcairo2 (>= 1.6.0), libcurl3 (>= 7.28.0), libglib2.0-0 (>= 2.12.0), libgomp1 (>= 4.9), libjpeg8 (>= 8c), liblapack3 | liblapack.so.3, liblzma5 (>= 5.1.1alpha+20120614), libpango-1.0-0 (>= 1.14.0), libpangocairo-1.0-0 (>= 1.14.0), libpcre3, libpng12-0 (>= 1.2.13-4), libreadline6 (>= 6.0), libtcl8.6 (>= 8.6.0), libtiff5 (>= 4.0.3), libtk8.6 (>= 8.6.0), libx11-6, libxt6, zlib1g (>= 1:1.1.4), ucf (>= 3.0), ca-certificates

Now, you have a point in that there are several curl packages available
within Debian / Ubuntu.  Here I use this:

edd at max:~$ COLUMNS=110 dpkg -l | grep "^ii  libcurl" | cut -c-78
ii  libcurl3:amd64        7.38.0-3ubuntu2 amd64           easy-to-use client-s
ii  libcurl3:i386         7.38.0-3ubuntu2 i386            easy-to-use client-s
ii  libcurl3-gnutls:amd64 7.38.0-3ubuntu2 amd64           easy-to-use client-s
ii  libcurl3-nss:amd64    7.38.0-3ubuntu2 amd64           easy-to-use client-s
ii  libcurl4-openssl-dev: 7.38.0-3ubuntu2 amd64           development files an
edd at max:~$

Now, I happen to deploy a fair number of similar machines also usuing Ubuntu
15.04 and work and _not one had issues_ when we switched to https for CRAN
repos.   But one critical thing you may be overlooking with R _before version
3.2.2_ is that you had to turn it on via options():

     ‘download.file.method’: Method to be used for ‘download.file’.
          Currently download methods ‘"internal"’, ‘"wininet"’ (Windows
          only), ‘"libcurl"’, ‘"wget"’ and ‘"curl"’ are available.  If
          not set, ‘method = "auto"’ is chosen: see ‘download.file’.

So play with that and download.file.
