Flat Field correction in ART is leave either a ghost in the center or a redish hue when testing FF DNGs

Hi. Deep breath and I did it - almost. Build it I mean. OK I managed to get, build and install LibRaw and mimalloc plus build the 1.14 (using Ocroquette as base How to build ART on Ubuntu 22.04 | ocroquette's technical Blog). Its a build run test before I try to add the fix agriggio / ART / commit / 8f12deb19d76 — Bitbucket but when I run ART I get this mimalloc error - libmimalloc.so.2: cannot open shared object file: No such file or directory. I saw in How to compile ART? - #12 by agriggio that mimalloc 2.0 is now included and should work. Is there a commit/fix I need to find and add before I build?
