I think your advise was a good one. Removing that file had the following
effect: instead of...

--8<---------------cut here---------------start------------->8---
checking for X... (cached) no
configure: error: in `/home/sva/src/clisp-2.48/src/clx/new-clx':
configure: error: cannot find X Window System
See `config.log' for more details.
make: *** [clx/new-clx] Error 1
--8<---------------cut here---------------end--------------->8---


... this is what I got when `make'ing CLisp:

--8<---------------cut here---------------start------------->8---
checking for X... (cached) libraries , headers 
checking for gethostbyname... (cached) yes
checking for connect... (cached) yes

checking size of KeySym... 4
checking for XGetAtomNames... yes

checking if XauGetAuthByAddr needs -lXau... no

Sounds better. Good enough?  We'll see...

Then, installing StumpWM...

git clone git://git.savannah.nongnu.org/stumpwm.git

cd stumpwm
autoconf

./configure --with-lisp=clisp

sudo cp /home/sva/src/stumpwm/contrib/stumpish /usr/local/bin/

But login out of Gnome and login into StumpWM does not work. StumpWM crashes
and the login manager notices that the session did not even last for 10
seconds...

More info is available in `~/.xsession-errors' it says. Here it is:
