"Permission denied" committing to sourceforge

Hi,

When trying to commit to a sourceforge repository using a self-compiled
SVN binary, I'm getting following error:

D:\temp\irrlicht>svn.exe commit --username HinzKunz -m "a message"
Authentication realm: <https://svn.code.sf.net:443> SourceForge User
Password for 'HinzKunz': ************
svn: E000013: Commit failed (details below):
svn: E000013: Can't create directory
'/svn/p/irrlicht/code/db/transactions/5634-1.txn': Permission denied

Could this mean that we have built the SVN binary incomplete (missing a
part that is required for committing to sourceforge but not other SVN
repositories)? How can I get some helpful logging? Thanks in advance.
