Attached are two scripts. find_fts.sh has to be in the PATH. It returns
the files specified at the command line, which contain unresolved
references to fts_* (e.g. "find_fts.sh /bin/*"). The other script
parses a +CONTENTS file of an installed port and hands over the
executables and libraries to find_fts.sh. If it finds a match, it
prints the port origin.

I let it run on my >800 installed ports via
for i in /var/db/pkg/*;do; ./analyse_ports_for_fts_abi_change.sh $i;done

It didn't find a match. I hope this is not because of a bug in my
script...

Bye,
Alexander.
