This is a problem with the automatic correction code. 
You have $correct set to "all". Tcsh tries to correct all the arguments,
Unfortunately it does not parse correctly the LIBDIR=$gnu/lib/emacs, and
tries to find if the whole directory exists.

If you unset correct, it works fine. It is impossible to determine what
the user really meant in cases like this. LIBDIR= could have been a
valid path component... [mkdir LIBDIR= LIBDIR=/usr ..]

I should add a `caveats' paragraph on that section of the manual page.
