Hello, Jeremy. This means that Apple's GCC (which I suspect is the one
you're using) builds to a target architecture that's different from
the one you chose during Fink installation. For example, Apple's GCC
defaults to 64-bit binaries on Mac OS 10.6, which would be a mismatch
if 32-bit Fink is installed.
In order to use the appropriate target architecture when building
programs against Fink packages, use
export PATH=/sw/var/lib/fink/path-prefix-10.6:$PATH
This is documented in the following FAQ entry:
http://fink.thetis.ig42.org/faq/usage-general.php#compile-myself
(on the temporary Web site)
Cheers,
