The most surprising thing is that I successfully built devel/pango from un privileged bootstrap for the very same version and on the very same system.

Actually, /home is a symbolic link to /usr/home on FreeBSD. If I manually change "-I/usr/home/triaxx/pkg/include/harfbuzz" to "-I/home/triaxx/pkg/include/harfbuzz" then hb.h is found.

If I compare the command line pasted in my previous message to the one given in output/build.ninja, then I have the feeling that g-ir-scanner resolves the symbolic links of the clfags argument before passing them to cc.
