I have pushed a complete re-implementation of the MEANS procedure, which I think fixes this problem.

After reading this bug report carefully and studying the output, it looks to me like proper support for pivot tables in the PSPP output engine is the solution.  That's something I'm working on, but it's not an easy fix, so it will take a while.

Zoltán Fábián <fabian@tarki.hu> reported on the pspp-users mailing list, archived at http://lists.gnu.org/archive/html/pspp-users/2015-01/msg00077.html, the following (the attachments are uploaded to this bug report):

User guide (version 0.8.4) writes:

"More than one table can be specified in a single command. Each table is separated by a ‘/’. For example
c d e BY x
/a b BY x y
/f BY y BY z.
has three tables (the ‘TABLE =’ is optional). The first table has three dependent variables c, d and e and a single categorical variable x. The second table has two dependent variables a and b, and two categorical variables x and y. The third table has a single dependent variables f and a categorical variable formed by the combination of y and z." (p. 139)

The emphasis is on the third table. PSPP produces two tables for means of f by y and mean of f by x, rather than one for mean f by combination of y and z.
SPSS can do it. I have attached two sample outputs. One for PSPP, and one for SPSS.
It would be very useful to resolve this issue.
