Compiling LO 6.2.0.3 get undefined reference to `hb_graphite2_face_get_gr_face'

I'm  having problems compiling 6.2.0.3 from the downloads

libreoffice-help-6.2.0.3.tar.xz
libreoffice-dictionaries-6.2.0.3.tar.xz
libreoffice-6.2.0.3.tar.xz
libreoffice-translations-6.2.0.3.tar.xz

The error I get is

I've come across this problem before and it went away somehow, not even 
sure if it was with LO. Inspecting my system I'd downloaded 
harfbuzz-1.8.8.tar.bz2 back in August 2018 and was comparing this with 
harfbuzz-1.8.4.tar.bz2. Can't remember what conclusion I came to! I 
firmly believe I don't use harfbuzz-1.8.8.tar.bz2 anywhere.

On my system I have harfbuzz-1.2.7-x86_64-1. However, I'm using the 
flags --with-system-icu and --without-system-harfbuzz which to me means 
I should be using the package 
https://dev-www.libreoffice.org/src/harfbuzz-1.8.4.tar.bz2.

What am I doing wrong or what point have I missed?
