ubuntu 20.5 build issues

[bebop-001]

I hit a couple of problems building under ubuntu. Autogeh.sh warns to install libtool. Under I had to install libtool-bin to get thr libtool executable.

configure crashed with:
./configure: line 15169: syntax error near unexpected token maximum' ./configure: line 15169: GNOME_COMPILE_WARNINGS(maximum)'
To fix this I needed to add gnome-common.
sudo apt-get install gnome-common
