Regression problem

We have tried to install the 6.4 on Solaris/Sparc 2.5.1, but the regression
test seems to be missing a few files. Can anybody shed any light on this?

We are using flex and gnu, but not gcc. We use the Sun C compiler - the
commercial one, not the bundled one.

This is the tail end of the regression test:

opr_sanity .. ok
create_function_1 .. ./regress.sh: sql/create_function_1.sql: cannot open
diff: expected/create_function_1.out: No such file or directory
ok
create_type .. failed
create_table .. ok
