HI Bill, Looks like we'll need to add a check against old version of cairo to prevent building against them. I presume most others don't have this issue because they are using more modern versions of cairo. I have 1.12.16 installed on my Kubuntu 12.10 that works fine. I wouldn't like to make this the minimum version though as older revs' should work fine too. So we have something between 1.8.8 that you have and 1.12.16 that I have.
FYI, I recall that Cairo deprecated/removed a set of functions that we used to use so I had to update the code to the new non deprecated equivlants, there is good chance in making these changes to be compatible with modern versions of Cairo backwards compatibility was lost for much older versions. Does any know of a list of Cairo features and when they were introduced? Robert.
