When trying to build remmina, these two header files

/usr/include/pango-1.0/pango/pango-coverage.h
/usr/include/pango-1.0/pango/pango-font.h

have

#include <hb.h>

but should be

#include <harfbuzz/hb.h>

Then the package builds fine.

Not sure if this is an issue with remmina or pango, but I only ran into the issue with remmina.
