[plug] bad interpreter message in Bash

[J Michael Gilks]

Just came across a new problem while trying to install Oracle on Mandrake 10.1
When I attempt to run the installer I get the following message

[oracle at angua mike]$ /mnt/cdrom/runInstaller
bash: /mnt/cdrom/runInstaller: /bin/sh: bad interpreter: Permission denied

The permissions are 

[oracle at angua mike]$ ls -la /mnt/cdrom
total 19
dr-xr-xr-x  7 root root 2048 Nov  2 15:48 ./
drwxr-xr-x  4 root root   96 Jan  5  2004 ../
dr-xr-xr-x  5 root root 2048 Nov  2 15:48 doc/
dr-xr-xr-x  5 root root 2048 Nov  2 15:48 install/

dr-xr-xr-x  8 root root 2048 Nov  2 15:48 stage/
-r-xr-xr-x  1 root root 5166 Oct 22 13:42 welcome.htm

I have tweaked the kernel settings as per instructions and as far as I can 
tell everything else seems to work OK.

Does anyone have any suggestions for what I have done wrong.

Thanks in advance.

Love
Mike.
