Revision r44621 supports (in a limited way) cairo 1.0 and hence I believe vanilla FC5 -- I found what purports to be a vanilla FC5 box and it works quite well there.
Two people have reported that the svg(), cairo-pdf() and cairo-ps() devices produce blank (but not empty) files. I was able to confirm that on Debian etch (cairo 1.2.4). They do work on cairo 1.4.14 (F8) and better on a 1.5.10 snapshot. We've got a working version on Mac OS X, but you need to install cairo. Finally, the quality of the fonts you see will depend on what fonts you have installed: if you only have X11 bitmapped fonts, that is what you will get (and I am getting on our minimally configured Debian etch machine). Our Fedora installations are mainly using the URW Type 1 fonts in the urw-fonts RPM. One of the alternatives is RH's liberation fonts (https://www.redhat.com/promo/fonts/).
