[BioC] Problems installing Genominator and GenomeGraphs

[Jose Lopez [guest]]

I already used

source("http://bioconductor.org/biocLite.R")
biocLite("Genominator")
Warning messages:
1: In install.packages(pkgs = pkgs, repos = repos, ...) :
  installation of package 'RCurl' had non-zero exit status
2: In install.packages(pkgs = pkgs, repos = repos, ...) :
  installation of package 'biomaRt' had non-zero exit status
3: In install.packages(pkgs = pkgs, repos = repos, ...) :
  installation of package 'GenomeGraphs' had non-zero exit status
4: In install.packages(pkgs = pkgs, repos = repos, ...) :
  installation of package 'Genominator' had non-zero exit status

I already tried with others packages and had no problem. 

Apparently is the biomaRt package, when tried to install it directly, I had the same problem. What do I need to do?

Thank you.
