-The Berkeley DB 1.85 coming with the Tru64 is unfortunately buggy.
-In general in Tru64 V4.* it seemed to be more stable, but in V5.*
-something broke (even though the DB stayed at release 1.85) and
-the DB_File extension test db-hash.t may fail by dumping core after
-the subtest 21.  There really is no good cure as of Tru64 V5.1A expect

--Dlocincpth=/some/include and -Dloclibpth=/some/lib when running Configure
-B<and> before running "make test" setting your LD_LIBRARY_PATH to /some/lib.
-
-You can also work around the problem by disabling the DB_File by
-specifying -Ui_db to Configure, and then using the BerkeleyFile module
-from CPAN instead of DB_File.  The BerkeleyFile works with Berkeley DB
-versions 2.* or greater.

+The DB_File tests (db-btree.t, db-hash.t, db-recno.t) may fail you
+have installed a newer version of Berkeley DB into the system and the
+-I and -L compiler and linker flags (watch out for Configure options
+-Dlocincpth and -Dloclibpth, and check your /usr/local/include and
+/usr/local/lib since they are included in Tru64 by default) introduce
+version conflicts with the DB 1.85 headers and libraries that came
+with the system (e.g. mixing a DB v2 library with the DB v1 headers
+is a bad idea).
+
+The second option is to explicitly instruct Configure to detect the

+C<-Dlocincpth=/some/include> and C<-Dloclibpth=/some/lib> B<and> before
+running "make test" setting your LD_LIBRARY_PATH to F</some/lib>.

+The third option is to work around the problem by disabling the
+DB_File completely when build Perl by specifying -Ui_db to Configure,
+and then using the BerkeleyFile module from CPAN instead of DB_File.
+The BerkeleyFile works with Berkeley DB versions 2.* or greater.

+The Berkeley DB 4.1.25 has been tested with Tru64 V5.1A and found
 to work.  The latest Berkeley DB can be found from F<http://www.sleepycat.com>.
