You don't need to do anything for sane-frontends.  It has *no* support
for infrared, period.  For sane-backends, you need a newer version of
the code[1], sane-backends-1.0.20 does not have the infrared support
yet.  It was added in sane-backends-1.0.21.

  [1] http://sane.alioth.debian.org/source.html

After extracting the archive,

  cd sane-backends-1.0.21/
  ./configure CPPFLAGS=-DSANE_FRAME_IR
  make
  sudo make install

should put an IR enabled epson2 backend and scanimage frontend below
/usr/local/.  If you do this, it is recommended to remove the Ubuntu
libsane package to avoid confusion.

After that

  scanimage -d epson2 -h

should be able to tell you what the relevant command-line option is.

Hope this helps,
