Postgres 7 on Alpha

Hi!

I have an old Alpha system which I use as a database server. I have
successufully run Postgres 6.5 on it but needed to upgrade to Postgres 7
to solve some problems. I downloaded the source of 7.0.2 as I could not
find any RPM of Postgres 7 for Alpha.

I compiled and installed it without a glitch but I can not initialize the
database. I get the following error:

bash$ /usr/local/pgsql/bin/initdb -D /usr/local/pgsql/data
This database system will be initialized with username "postgres".
This user will own all the data files and must also own the server
process.

initdb failed.
Removing /usr/local/pgsql/data.
Removing temp file /tmp/initdb.26953.

I run Red Hat Linux release 6.2 (Zoot), Kernel 2.2.14-6.0 on an alpha.
What do I do now? What is a spinlock?
