Installation trouble

I'm having difficulty installing 8.0.4. Server is SuSE 8.2 without PG
installed. However some client libraries are Yast installed due to
dependency reconciliation.

I'm doing the standard install (./configure, make, make install) and
have created the postgres user and appropriate data directory but
when I run:

initdb /var/lib/pgsql/data

I get:

initdb: file "/usr/share/postgres.bki" does not exist
This means you have a corrupted installation or identified
the wrong directory with the invocation option -L.

Running:

initdb -L /usr/local/pgsql/share/ /var/lib/pgsql/data

Looks pretty good at first but fails at:

creating conversions ... FATAL: could not access file
"$libdir/ascii_and_mic": No such file or directory

Reports from pg_config:
--libdir: /usr/lib
--bindir: /usr/bin
--configure: -blank-
--includedir-server: /usr/include/server
--includedir: /usr/include
--pgxs: /usr/lib/pgxs/src/makefiles/pgxs.mk
--pkglibdir: /usr/lib

Note, the directories shown for libdir, bindir, includedir and such
are not where the files were actually installed.

Now I could just start shuffling files around till things work but
since I've installed/upgraded many PG installations without this
difficulty I suspect there is something basic that I'm missing that
is causing all of the trouble. Suggestions?

Cheers,
Steve
