I have configured and made postgresql according to its INSTALL
instructions
on a RedHat 7 pc system.

I have added the appropriate line in /etc/ld.so.conf as suggested
pointing to
the lib directory under the postgresql installation. Such directory
does exist
and contains:

bash-2.04$ ls -al /export/home/postgres/postgresql-7.0.3/lib

I have configured postgress with and without a --libdir definition and
the
get the same result on the regression testing attempts.

The src/test/regress/run_check.sh sets PGLIB="$LIBDIR" but I have not
been able to figure out how $LIBDIR should have been set, whereas now
it seems not to be set. I have not been able to find any reference to
PGLIB
in the postgresql documentation.

Any assistance would greatly be appreciated.
