Most probably, pmodstub.exe isn't in the directory where you type the
above command.  That's the dumb DOS COPY command you are using, remember? 
It doesn't know how to look for the files you need, it needs you to tell
you where to find pmodstub.  So you should say something like this: 

	copy /b c:\djgpp\bin\pmodstub.exe + who who.exe

(assuming you put pmodstub.exe into c:\djgpp\bin).  Make sure that COPY 
prints the names of *both* pmodstub.exe and who when it copies, because 
if it doesn't find one of the files, it just copies the rest without
any error messages.

That's because you just effectively copied who into who.exe.  Since who is
raw COFF image, DOS doesn't know how to run it, so it tries to interpret
its beginning as a COM program (because it doesn't have the MZ signature),
with obvious results.
