That is not "the official bundle" - that is merely a convenience binary for the Cairo package (not to be confused with cairo back-end in R) for users that don't have cairographics installed on their system. I don't think that CRAN uses this for R builds. > Perhaps also wasn't clear in the bugzilla thread - everybody from > fontconfig/cairo/freetype involved knew it being the issue so it has never > been explicitly spelled out - the problem was (is) with cairo's pdf/ps > generation, aided by freetype. > But then why would even the old binary in the Cairo package be an issue? It uses Win32 API, not freetype.
