There may be no path to success from 8.2.  I have a vague memory that a
colleague at work starting running into problems like this (ctfmerge was
one of them I think), and we played with things for a few hours
(WITHOUT_CTF in make.conf only got us on to a new problem).  Eventually
we gave up and updated his machine to 8.4.  That was for building
11-current but it may apply to 10 as well.
