'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.

Sergei.
