I'm not a luatex user, but I find the error message puzzling. It appears to be
referring to a colon-separated list of directories as though it were a single
file or directory name. Is there something in your package that's preventing
the colon from being recognized as a separator? Are you perhaps mixing Cygwin
and Windows path conventions?
stack traceback:
[C]: in function 'lfs.dir' > ./fonts.ptxlua:285: in local

\inputluafile ...ua {dofile(kpse.find_file("#1"))}

?
```
Which is weird, because my program works correctly in the windows
version of TeXLive, and `ls /cygdrive/c/windows/fonts` returns the
directory listing correctly.
I don't read the error message as referring to that directory alone.
