Well that at least let me know that there was a problem with USB:
	"configure: error: USB support requested but required libraries not found."
But that's fixed with pkg-config (below)

I could fix that.

Didn't know about that one — it WORKED! THANKS!

I'm used to that ;)

um, are there _any_ OSX specific instructions? If so I've totally missed them all these years that I've been relying on SANE :)

So I'm past ./configure,  Now I get the following error from MAKE:

~/Downloads/sane-backends-1.0.29-116-g336cbdfd$ sudo make

make[1]: *** [sanei_usb.lo] Error 1

This is specific to 1.0.29, as I tried 1.0.28 and it continues to install OK, (but I have to add my scanner to fujitsu.conf.) I'd still like to try to fix this in 1.0.29.
