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.

I think I have identified the problem with the .work.log file.

We can notice in the command line which produces the error message that some -I arguments are provided with the "/home/triaxx/pkg/include" directory while other are provided with the "/usr/home/triaxx/pkg/include". 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.

Now, I could not explain why hb.h is not found when the canonical path "/usr/home/triaxx/pkg/include/harfbuzz" is provided to the compiler.

$ ls -l .buildlink/include/harfbuzz/hb.h 
lrwxr-xr-x  1 triaxx  triaxx  38 28 avr.  15:36 .buildlink/include/harfbuzz/hb.h -> /home/triaxx/pkg/include/harfbuzz/hb.h
