Non zero exit status error when installing a package in linux - r

Question

I just installed R on linux. Now I try to install some packages on it. When I try on install the
the RCurl package using:
install.packages("RCurl")
I however get the following:
* installing *source* package ‘bitops’ ...
** package ‘bitops’ successfully unpacked and MD5 sums checked
** libs
gcc -std=gnu99 -I/usr/share/R/include -DNDEBUG -fpic -O3 -pipe -g -c bit-ops.c -o bit-ops.o

The downloaded source packages are in

Warning message:
In install.packages("RCurl") :

In the beginning everything seems to go fine but then I trows a non-zero exit status error. Any thoughts
what goes wrong here?
