cvs2svn.py can't access cvs db

[Roman Schlegel]

I am trying to get my data from the cvs to the new svn repository,
both on a sparc solaris 5.8 system.
- The python package 2.3.3 is from http://sunfreeware.com
- bsddb3-4.2.4 from http://pybsddb.sourceforge.net
- Berkeley DB 4.2.52 from http://www.sleepycat.com
- Subversion 1.0.2 from http://subversion.tigris.org
- CVS 1.11

Not even a dump from an existing cvs repository works:

$ cvs2svn.py --dump-only --dumpfile test.dump /path/to/my/repos
Traceback (most recent call last):
  File "cvs2svn.py", line 3211, in ?
    main()
  File "cvs2svn.py", line 3201, in main
    ctx.default_branches_db = Database(DEFAULT_BRANCHES_DB, 'n')
  File "cvs2svn.py", line 192, in __init__
    self.db = anydbm.open(filename, mode)
  File "/usr/local/lib/python2.3/anydbm.py", line 83, in open
    return mod.open(file, flag, mode)
  File "/usr/local/lib/python2.3/dbhash.py", line 16, in open
    return bsddb.hashopen(file, flag, mode)
  File "/usr/local/lib/python2.3/site-packages/bsddb3/__init__.py",
line 293, in hashopen
    d.open(file, db.DB_HASH, flags, mode)
bsddb._db.DBInvalidArgError: (22, 'Invalid argument -- DB_TRUNCATE
illegal with locking specified')

If I run "run-tests.py", the output is as follows:

$ run-tests.py -v
CMD: cvs2svn.py <TIME = 0.916313>
PASS:  run-tests.py 1: cvs2svn with no arguments shows usage
CMD: cvs2svn.py "--bdb-txn-nosync" "-s" "main-svnrepos"
"/opt/cvs2svn/test-data/main-cvsrepos" <TIME = 9.206150>

/opt/cvs2svn/cvs2svn.py said:
