du4.0d build fails, SUBSYS.o

Dear All,

getting this trying to build 6.4.2 on my du4.0d system.

for i in buffer file ipc large_object lmgr page smgr; do gmake -C $i
buffer/SUBSYS.o; done
gmake[3]: Entering directory
`/usr/local/src/postgresql-6.4.2/src/backend/storage/buffer'
gmake[3]: *** No rule to make target `buffer/SUBSYS.o'.  Stop.
gmake[3]: Leaving directory
`/usr/local/src/postgresql-6.4.2/src/backend/storage/buffer'
gmake[3]: Entering directory
`/usr/local/src/postgresql-6.4.2/src/backend/storage/file'
gmake[3]: *** No rule to make target `buffer/SUBSYS.o'.  Stop.

Any ideas how to get this made please? Been browsing the recent archives,
but not noticed any ref. to this, though may have missed it.

Cheers,

Bob Parkinson
