Comment(by ryandesign@…):

 Interesting:

 {{{
 cairo-mutex-impl-private.h:262:3: error: #error "XXX: No mutex
 implementation found.  Cairo will not work with multiple threads.  Define
 CAIRO_NO_MUTEX to 1 to acknowledge and accept this limitation and compile
 cairo without thread-safety support."
 }}}

 I have not seen that before. I'll have to investigate.
