I don't believe you transcribed your query accurately.
My attempt to replicate the complaint works fine:

nic=# create table a (one int, two int);
CREATE
nic=# create table b (two int, three int);
CREATE
nic=# create table c (two int);
CREATE
nic=# select a.one, b.two, c.two
nic-# FROM a INNER JOIN b ON a.one = b.three
nic-# LEFT OUTER JOIN c on a.one = c.two;
one | two | two
-----+-----+-----
(0 rows)

I can get the same error message with:

nic=# select a.one, b.two, c.two
nic-# FROM a INNER JOIN b ON a.one = c.two
nic-# LEFT OUTER JOIN c on a.one = c.two;
NOTICE: Adding missing FROM-clause entry for table "c"
ERROR: JOIN/ON clause refers to "c", which is not part of JOIN

which is correct since the a/b join should have a join condition
that refers only to a and b.
