I see in the zip file that the file name is actually lang.H64
I.E. a capital 'H'. So I'm guessing that the glob done
by the shell is case insensitive, while the file system
is only case retentive and so maps the lang.h64 request to lang.H64?

In bash for example you can run the following to
glob case insensitively:

  shopt -s nocaseglob

I've no experience on such platforms so the above is just a guess,
and we can open the bug again if there is an issue.

thanks,
Pádraig.
