I just tried building postgres from CVS and when I 'gmake check' I get this:

---------------------

pg_regress: initdb failed
Examine ./log/initdb.log for the reason.

gmake[2]: Leaving directory `/home/chriskl/pgsql/src/test/regress'
gmake[1]: Leaving directory `/home/chriskl/pgsql/src/test'

--------------------

OK, let's look at the log:

--------------------

chriskl@database:~/pgsql$ tail src/test/regress/log/initdb.log

Any ideas?
