So, what's this? I didn't even know cairo had an --enable-pdf switch. I only use cairo for graphviz, and one of the features graphviz gains by using cairo is the ability to output pdfs. This has always worked for me, though I've never used --enable-pdf. So does --enable-pdf get us anything extra? I see from ./configure --help that the default for this option is "auto" so maybe for me it was automatically on and for you it was automatically off? I wonder what influences this automation. Does the pdf ability need any additional dependencies? If not, shouldn't we enable pdf all the time rather than putting it in a variant?
