Comment (by kencu):

 Most likely it should be
 {{{
 libdir=${prefix}/lib
 }}}
 and leave "exec_prefix" right out of the file, like homebrew's has:

 {{{
 % cat ./lib/pkgconfig/cairo-script-interpreter.pc

 prefix=/opt/homebrew/Cellar/cairo/1.18.0
 includedir=${prefix}/include
 libdir=${prefix}/lib

 Name: cairo-script-interpreter
 Description: script surface backend for cairo graphics library
 Version: 1.18.0
 Requires: cairo
 Requires.private: zlib, libpng, fontconfig >=  2.2.95, freetype2 >=
 9.7.3, x11, xext, xrender >=  0.6, xcb >=  1.6, xcb-render >=  1.6, xcb-
 shm, pixman-1 >=  0.36.0, lzo2
 Libs: -L${libdir} -lcairo-script-interpreter
 Libs.private: -lm -ldl -framework CoreFoundation -framework
 ApplicationServices
 Cflags: -I${includedir}/cairo
 }}}

 no idea why MacPort's .pc file is different, but I see our cairo is out of
 date compared to theirs, so perhaps start with that...
