netbeans 6.5 installer issue

on my second Ubuntu Hardy (64-bit) i got an issue with installing netbeans 6.5beta:

~/Desktop$ ./netbeans-6.5beta-linux.sh
bash: ./netbeans-6.5beta-linux.sh: /bin/sh: bad interpreter: Text file busy

googled a litte bit and found a tip from morris 007:

my file permission were corret, yet, but starting installer with sh solved above error message:

~/Desktop$ sh netbeans-6.5beta-linux.sh
Configuring the installer...
Searching for JVM on the system...
Extracting installation data...
Running the installer wizard...


Interesting is also, that there seems to be differences between the MacOS and Linux distribution of Netbeans 6.5beta.
On MacOS i didn’t got the “select pack” screen during installation procedure:

netbeans installer select packs
