In very old versions of fink, the search order used to be from left to 
right in the Trees line (or so the documentation said). Nowadays it 
seems to be from right to left. This is, of course, not reasonable, 
given that local/main is by default still the first item on that line 
but should be searched first.

In reality you should not depend on that search order. It is not only at 
build time where this can lead to confusion. Also at install time, if 
you built packages with identical version-revision in two different 
trees, you have to pray that dpkg finds the right one of the deb files 
with identical names.

The better solution is to increase the revision for the info file in 
your local tree: If you have foo-1.2-3 in unstable, make it foo-1.2-3.0 
or similar in local. This has the advantage that once the revision in 
unstable is increased to foo-1.2-4, it will supersede the one in local, 
which is often what you want.
