Maybe, but then guix also needs to use pkg-config to find out the right -I 
flags.

Currently, when trying "guix build gtk", which has pango as input, the 
CPATH contains
   /nix/store/ac9zyl88qyp6gbidcyrzj8rdngbkqppr-pango-1.34.1/include ,
whereas pango.pc contains the line
   Cflags: -I${includedir}/pango-1.0
And compilation stops with the expected error:
In file included from ../gdk/gdkscreen.h:32:0,
                 from ../gdk/gdkapplaunchcontext.h:31,
                 from ../gdk/gdk.h:32,
                 from gtkaccelgroup.h:35,
                 from gtkaccelgroup.c:31:
../gdk/gdktypes.h:37:25: fatal error: pango/pango.h: No such file or 
directory
compilation terminated.
