 This might be caused by old version pkg-config. Upgrading pkg-config
 from 0.15.something to 0.21 fixed the problem for me. A clue in the log
 output was cairo's configure script checking for pkg-config >=3D 0.19, bu=
 t
 proceeding regardless.
 
 Attached below is a small piece from the configure of a failing build,
 staring from failure to find pkg-config of at least version 0.19:
