Regression Test errors

Hey guys/gals;

Postgre 6.4.2 seemed to compile fine on my system, but running the
regression test revealed several notable errors all related to an undefined
symbol: assert_enabled

>ERROR: Load of file /usr/src/pgsql/src/test/regress/input/../regress.so
failed: /usr/src/pgsql/src/
>test/regress/input/../regress.so: undefined symbol: assert_enabled

The test which are failing as a result of this error are:
create_function_2
triggers
misc
alter_table

Can you point me to a solution?

Specifics:
Postgre 6.4.2
Redhat 5.2
Pentium 100 box / 32 meg ram.

Regards,
Sean.
