> Can someone please send me the workaround!!

I've just installed the patch below which should silence those errors
(tho the error will still be there and will prevent completion from
working).

Gentlemen, as you know when you do M-x man and get the prompt
   Manual entry (default blabla):
there is no TAB completion.

Well as many of the man pages are the same names as shell commands, why
not just use the same completion as shell-command and
shell-command-on-region use?

It's better than nothing, and one can still enter other names too.
