Three times, anyway.

# xsane --version
xsane-0.70
  package xsane-0.70
  SANE-1.0
  compiled with GTK-1.2.8
  with GIMP support, compiled with GIMP-1.2.0
  XSane output formats: jpeg, png, pnm, ps, raw, tiff

It was installed via the debs, and that's the newest version available
from the unstable distribution.

No, I haven't touched it.  My last few installs were done with:
# cvs update && ./configure && make && make install

Ah.  Noted for future reference.
