v6.4.2 not working on AlphaLinux

Greetings --

I have been attempting to get PostgreSQL working on my AlphaLinux box,
with limited success.  Here are the stats for my system:

- PostgreSQL: v6.4.2
- OS: RedHat v5.2 Linux v2.0.35 (glibc 2.0.7-19)
- Hardware: DEC Alpha 21164 (from Aspen Systems)

I was able to compile everything, and eventually init the database.
However, during 'initdb', and in subsequent regression tests, I kept
getting the following error:

FATAL: s_lock(5556c120) at spin.c:114, stuck spinlock. Aborting.

This appeared to be the cause for some of the regression test
failures, though not for all of them.  Attached is a copy of my
regress.out file.

If you need further info, please feel free to contact me.  We would
very much like to use this database in a new product we are developing
on this platform.

Thanks in advance,

postmaster must already be running for the regression tests to succeed.
The time zone is now set to PST8PDT explicitly by this regression test
 client frontend. Please report any apparent problems to
   ports@postgresql.org
See regress/README for more information.
