[sane-devel] help compiling sane

[Paul Newall]

Rafe,
You could try this search:  find /usr -name libsane.s*
it may take a few minutes to finish, but should find all your sane 
backend installation directories.
On a live DVD of ubuntu 14.10 sane seems to be in /usr/lib/x86_64-linux-gnu

Also run: scanimage -V
That tells you which version of sane is actually running. If it gives 
you version 1.0.24 that's the original ubuntu version, not the one you 
have compiled.

The bottom section of this page 
https://help.ubuntu.com/community/CompileSaneFromSource
Says something about how to specify which installation of sane is used.
