Hello,
I noticed I've a recurring problem, often, when I want to install a package, it displays this :

> install.packages('leaflet')
Installing package into ‘/home/bessy/R/x86_64-pc-linux-gnu-library/3.1’
(as ‘lib’ is unspecified)
Warning in install.packages :
  package ‘leaflet’ is not available (for R version 3.1.1)

does someone know how resloving this problem ?

The leaflet package isn't on CRAN yet. You need to use these commands to install directly from GitHub instead:

install.packages("devtools") # if necessary 

devtools::install_github("rstudio/leaflet")

RCurl is failing to install because it relies on libcurl being installed. If you're on Ubuntu, you can do it like this:

sudo apt-get install libcurl4-openssl-dev
