The huge libtool work that have past should have fixed the situation
It might be interesting to get exp-run with that patch (on freebsd 10)
to see what happen
Some ports seem to have succeeded but the packages are missing some files, e.g. libiconv:
Currently the message printed by the fix (===> FreeBSD 10 autotools fix applied to...) is always shown even if there are no changes to a file. If it were only shown if file and file.fbsd10bak are different (using "cmp -s"?) it would be easier to find out which ports still need it.
