You removed the Fedora package.  That also means that the files below
/etc/sane.d/ are probably all gone as well as the udev .rules file that
is responsible for setting up read/write access to the device for users
other than "root".

If you ran configure without a --prefix option, everything got installed
below /usr/local/, including the configuration files.  That should not
be a problem though (since you removed the Fedora package) and scanimage
should find the genesys.conf file below /usr/local/.  That file should
have an entry for the LiDE 120.

I think your problem stems from the fact that the udev .rules didn't get
installed in a place where udev looks.  If my thought is right you
should be able to find the scanner with

  sudo scanimage -L

and scan by prefixing your command with `sudo`.

If that works, you can "fix" things with

  make -C tools udev/libsane.rules
  sudo cp tools/udev/libsane.rules /etc/udev/rules.d/

That page is out-of-date :-(

Hope this made sense,
