Hi, Sorry if I am not very knowledgeable;
I installed scanimage and sane on a Mac running 10.6 and it works from command
line. (http://www.ellert.se/twain-sane/)
But xsane, which I installed from MacPorts, which took many hours of compiling
things, does not find any devices, even though I can
Just a guess since you didn't mention working around following.
Macports is installed under /opt's and only looks for its libraries under
/opts. I think those twain-sane packages are self-contained packages.
So probably when you compiled xsane from Macports it pulled in the older
sane-backends-1
