[R-sig-Debian] bug in r-cran-curl from c2d4u

[Jeroen Ooms]

On Bionic with c2d4u I see:

The following packages have been kept back:
  r-cran-curl

The problem is that r-cran-curl from 2d4du has a runtime dependency on
libcurl4-openssl-dev. This dev package cannot be installed in
conjunction with libcurl4-gnutls-dev (which again is required by some
other packages).

This is a bug because libcurl4-openssl-dev should be a build-depends
only, the runtime depends is 'libcurl4'. The debian r-cran-curl
package has got this correct, perhaps we can just upload the debian
package to 2cd4u? https://packages.debian.org/buster/r-cran-curl

Thanks!
