issues on 9.4 while upgrading pango - missing cairo

Hi,

while upgrading my ol' sparcstation with pkg_rolling-replace I hit this
issue:

[95/159] Generating pango/PangoCairo-1.0.gir with a custom command
(wrapped by meson to set env)
FAILED: pango/PangoCairo-1.0.gir

fatal error: cairo.h: No such file or directory
 #include <cairo.h>
          ^~~~~~~~~
compilation terminated.
Traceback (most recent call last):

cairo is installed (I forced, to be sure, I forced a replace manually)
cairo-1.18.0nb1     Vector graphics library with cross-device output support


find /usr/pkg/ -name cairo.h
/usr/pkg/include/cairo/cairo.h

this looks identical to what I see on a "working" 10.0 system

In the command line I see:
-I/usr/pkg/include/cairo

which looks correct and mathing to the file I found!

Where is the catch?
