This is an old problem: how to install SANE from git beside standard
libsane. There is no easy to read manual available.

We should add something like the description below to README.linux. I
tested this with (K)Ubuntu (10.04, 12.04), LinuxMint (LMDE, 12, 13) and
Fedora 17.

(1) Find the location of standard libsane. It's different for each
distribution. On 64 bit Ubuntu 12.04 it is here:
'/usr/lib/x86_64-linux-gnu/'. On 64 bit Fedora 17 it is here: '/usr/lib64/'.

(2) Decide where you want to install the new SANE version.

(2.1) You can overwrite standard libsane. Then you need to do some extra
configuration for SANE: './configure
--libdir="/usr/lib/x86_64-linux-gnu"'. Here you need to use the path
found in (1). If you also want to replace the binaries, configuration,
translations, etc. please read './configure --help'.

(2.2) You can set symbolic links to the new driver. I assume that the
path found in (1) is '/usr/lib/x86_64-linux-gnu/' and new SANE has been
installed to '/usr/local/lib/':
cd /usr/lib/x86_64-linux-gnu
sudo ln -sf /usr/local/lib/libsane.so.1.0.23 libsane.so.1
sudo ln -sf /usr/local/lib/sane/libsane-pixma.la .

(3) Copy 'tools/udev/libsane.rules' to '/etc/udev/rules.d/'.

(4) To avoid using the scanner with root rights, add your user to the
group 'scanner'. If this group doesn't exist you must create it (I
needed to do this in Fedora 17).

(5) Reconnect your scanner to the USB bus and logoff/login if you needed
to do (4) or just reboot.

Cheers,
Rolf
