weird regression test issue CVS HEAD

[Christopher Kings-Lynne <chriskl(at)familyhealth(dot)com(dot)au>]

I keep getting this:

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

rm regress.o
gmake[2]: Leaving directory `/home/chriskl/pgsql/src/test/regress'
gmake[1]: Leaving directory `/home/chriskl/pgsql/src/test'
-bash-2.05b$ more src/test/regress/log/initdb.log

me/chriskl/local/share/postgresql/postgres.bki" does not belong to 
PostgreSQL 7.

Check your installation or specify the correct path using the option -L.
-bash-2.05b$

I wiped the src/test dir, re cvs up'd and did gmake test again and it 
still happens.  What's going on?
