Trying to build graphics/sane-backends (dependency of graphics/xsane)
on MacOS X 10.1.5 and 10.2.8 fails linking as follows:

[...]

Stop.

I've seen other packages that had multiply-defined symbols fail this
way too, but when I tried building them later, after unspecified
fixes had been applied, they simply ignored the error and went ahead
and as far as I know, they worked.

Perhaps the same treatment applies here?

Thanks.
