When both CodeLibrarian and OPM ExtraHighlighters package are used, two different versions of synhighlighterlua.pas file are used and Lazarus first reports "checksum changed" error and the later also "incompatible ppu" error.
I guess that this could be fixed if CodeLibrarian would not hold it's own copy of SynEdit highlighters, and instead of that depend on OPM ExtraHighlighters package.
