 cairo installs 19 pc files, all of which reference exec_prefix and all but
 one of which define exec_prefix, so I'd call that a clear bug in cairo.

 Oh right: we're out of date because we're not using meson with cairo yet,
 and it's a bit of work to convert the portfile to use meson, which is
 necessary to update any further as they've removed the autotools build
 system. That's #66852.
