I see we have a serious problem here. *_ROOT are used in many places in 
ACE,
hence it is rather difficult to remove this dependency. I recall, I 
prepared once a
RPM distribution for ACE. I did not even tried to modify ACE source to 
get rid of
these variables. Instead I created a post-install script, which added 
some variables
to system profile. It was easy for RedHat I used, because it had 
/etc/profile.d/ folder,
where post-install scripts could write their settings eg. 
/etc/profile.d/ace.sh with export
ACE_ROOT=/usr.

Do you  know if Debian provides a similiar method for setup? I agree, 
that all those
*_ROOT variables just pollute the environment, but this ensures that 
everything is
configured correctly. Hove no other idea how to manage the problem 
globally :-(
