Since cairo is already installed (and actually required by gtk2
anyway), there is no need to install it again.

There are plenty of explanations in this error message.

First,

$ pkg-config --modversion cairo

should return 1.4.10.

If it doesn't, then you should look for a cairo.pc file in
/opt/local/lib/pkgconfig
If it is there, then this probably just that you must set 
PKG_CONFIG_PATH explicitly to the above directory.
Otherwise, search for cairo.pc, and add the directory.

This should solve your problem.
