'ld' suggests you what to do:

"
'cairo_set_source_rgb' is defined in DSO /usr/lib/gcc/i686-linux-gnu/4.6/../../../i386-linux-gnu/libcairo.so so try adding it to the linker command line
".

I.e. in your case 'cairo' library is apparently not in 'ld' default search path, it's (if I make "calculations" correctly) under

/usr/lib/i386-linux-gnu/

directory.

Or maybe 'cairo' development package is not installed.
