  Add slgtk (includes imdisplay) to an isis installation.
  These steps assume a [debian] linux system where the isis
  installation was made by doing install-isis.sh in the
  directory </my/install/isis/dir>.  This creates the two
  subdirs: '/isis-build and '/x86_64-unknown-linux-gnu 
  which appear below.


  ---gtk---  From: apt-get
su
apt-get install gtk+2 gtk+2-dev
  (1.5 Gb added?!)
  JED says that slgtk [only] needs this:
apt-get install libgtk2.0-dev
  this is already all installed from the previous apt-get.
exit   [from su]
  Can then do a bunch of demos from:
[/usr/bin/] gtk-demo


  ---slirp---  From: http://www.jedsoft.org/snapshots/
  Need slirp too
  Downloaded slirp-pre2.0.0-23 to </my/install/isis/dir>/isis-build  
cd </my/install/isis/dir>/isis-build/slirp-pre2.0.0-23
./configure \
    --with-slang=</my/install/isis/dir>/x86_64-unknown-linux-gnu    \
    --prefix=</my/install/isis/dir>/x86_64-unknown-linux-gnu
make
make check     <-- will indicate "passed"
make install


  ---slgtk---  From: http://www.jedsoft.org/snapshots/
  Downloaded slgtk-pre0.8.0-8 to </my/install/isis/dir>/isis-build
  In there do these steps to build slgtk
  into the install-isis s/w:
cd </my/install/isis/dir>/isis-build/slgtk-pre0.8.0-8
./configure  \
    --with-slang=</my/install/isis/dir>/x86_64-unknown-linux-gnu  \
    --prefix=</my/install/isis/dir>/x86_64-unknown-linux-gnu  \
    --with-slirp=</my/install/isis/dir>/x86_64-unknown-linux-gnu/bin/slirp  \
    --with-gtk=/usr
    
make > build.log 2>&1 &
make check     <-- a bunch of test windows appear
make install
