[sane-devel] GT68xx/Visioneer 7400 scans reddish?

I have configured SANE built from MacPorts (sane-backends
@1.0.22_0+universal) for the Visioneer OneTouch 7400 scanner, similarly to
what's mentioned in [sane-devel] How to get Visioneer Onetouch 7400 working,
but the result is somewhat strange: all color scans have a reddish hue, and
various adjustments in xsane don't help. I have an example scan
(including the calibration area as discussed in debugging the GT68xx
backend) and verbose (255) log, but don't really know what's going on in
there. The same scanner works fine under Windows with the vendor driver
(aside from the bundled software being a bit cr*p...). Suggestions?

Both files generated by the command:
scanimage -d gt68xx:libusb:036:005 -p -B --mode Color --depth 12
