[igraph] igraph: Trouble upon install in Ubuntu 17.04

[Cedric Bhihe]

Hello,

I'm new to igraph and still green on R ('littler' version 0.3.2, with R v3.4.0)  and Rstudio (Version 1.0.153).

I just installed R and Rstudio and am experiencing problems when installing igraph on Ubuntu 17.04 (64bits).

The install error described below seems to be independent of the library directory in which I try to install the package. I tried both:
[1] "/home/ckb/R/x86_64-pc-linux-gnu-library/3.4"
[2] "/usr/local/lib/R/site-library"
     ... by modifying the file /etc/R/Renviron.
The result is in each case:

=====================================

=====================================

Can anyone help with a fix so I can proceed with the install ?

Thanks.
