install jdk-1_5_0_04-linux-i586.bin fails with "too many arguments"

["Randall J. Parr" <RParr@TemporalArts.COM>]

I am trying to install the Sun JDK 1.5.0_04 on sarge (moving on to 
testing) and it fails as below.

# sh jdk-1_5_0_04-linux-i586.bin 
.......
.......
Creating jdk1.5.0_04/jre/lib/javaws.jar
Creating jdk1.5.0_04/jre/lib/deploy.jar
dirname: too many arguments
Try `dirname --help' for more information.
dirname: too few arguments
Try `dirname --help' for more information.


Anyone have a fix for this?  I'd really rather avoid having to tear into 
thier install script if its already known how to fix it.

Thanks
