Strange error during ports upgrade

[Jack Raats]

After running cvsup and making the index file I'll get the following
warnings/errors

heaven# make index
Generating INDEX - please wait..zh-openoffice-CN-1.0.3_2:
"/usr/ports/devel/jakarta-ant" non-existent -- dependency list incomplete
zh-openoffice-TW-1.0.3_2: "/usr/ports/devel/jakarta-ant" non-existent --

postgresql-jdbc-7.3.3: "/usr/ports/devel/jakarta-ant" non-existent --

What's wrong???

Met vriendelijke groeten,
