That got me to showstopper #2: (lengthy warniing)

       Consider adjusting the PKG_CONFIG_PATH environment variable if you
       installed software in a non-standard prefix.

       Alternatively, you may set the environment variables DBUS_CFLAGS
       and DBUS_LIBS to avoid the need to call pkg-config.
       See the pkg-config man page for more details.

There is help there, but to me its engrish. Next fix?

Thank you Mark Bourne, this looks like actual progress in what has 
turned into a cast iron bitch.
I'll not touch that shell till the next advice is tendered. However 
"echo $PKG_CONFIG_PATH" is
null in this venv.


Cheers, Gene Heskett.
