Configuration failed because libcurl was not found. Try installing:

* rpm: libcurl-devel (Fedora, CentOS, RHEL)

If libcurl is already installed, check that 'pkg-config' is in your
PATH and PKG_CONFIG_PATH contains a libcurl.pc file. If pkg-config
is unavailable you can set INCLUDE_DIR and LIB_DIR manually via:
R CMD INSTALL --configure-vars='INCLUDE_DIR=... LIB_DIR=...'

Então, quando eu tentei instalar libcurl4 , de alguma forma minha árvore de dependência errou:

Como posso resolver a árvore de dependências sujas para instalar readr em R com sucesso?
Sempre que você tiver um problema de dependência, execute:
sudo apt-get install -f
Agora, para instalar readr em R e, para o caso do Ubuntu 16.04 e R versão 3.2.3 (2015-12-10), tive que fazer o seguinte:
sudo apt-get install libcurl3
sudo apt-get install libcurl4-gnutls-dev
Os dois comandos a seguir resolveram meu problema
apt-get -y build-dep libcurl4-gnutls-dev
apt-get -y install libcurl4-gnutls-dev
