I want to install FastRWeb for R but it requires some Cairo. How can I install the Cairo?

compilation terminated.
make: *** [xlib-backend.o] Error 1
ERROR: compilation failed for package ‘Cairo’
* removing ‘/home/xfz/R/i686-pc-linux-gnu-library/2.13/Cairo’
ERROR: dependency ‘Cairo’ is not available for package ‘FastRWeb’
* removing ‘/home/xfz/R/i686-pc-linux-gnu-library/2.13/FastRWeb’

The downloaded packages are in
    ‘/tmp/Rtmpno8hhF/downloaded_packages’
Warning messages:
1: In install.packages("FastRWeb", , "http://rforge.net/", type = "source") :
  installation of package 'Cairo' had non-zero exit status
2: In install.packages("FastRWeb", , "http://rforge.net/", type = "source") :

I cannot find what the Cairo is here, 16 entries with this search term below. It is apparently some library.

$ apt-cache search libcairo|wc
     16     132     996
