I have a strange scenario (ooh missus)... When logged on as a super user, the only way I can connect to a database is by issuing the unset LIBPATH command before running my script. I have tried numerous ways to replicate this command within my script such as 
1/
$command = 'unset LIBPATH';
system( $command  );

but get the error Can't exec "unset": A file or directory in the path name does not exist. 
$ENV{LIBPATH} = ""

[download]
and 
$ENV{LIBPATH} = '/usr/lib:/lib:/home/db2inst1/sqllib/lib'

[download]
and 
delete $ENV{LIBPATH};

[download]
and 
system("LIBPATH=/usr/lib:/lib:/home/db2inst1/sqllib/lib; export LIBPAT
+H");

[download]
and 
$ENV{LIBPATH} = $ENV{ LIBPATH } . ":/lib:/home/db2inst1/sqllib/lib";

Whilst these appear to have set the $ENV{LIBPATH} correctly, I still get the error message

The ONLY thing that seems to allow me to connect is running the 'unset LIBPATH' command before I run my script. Now I appreciate that I'm not supplying a whole heap of code here, but I just wonder if anyone has encountered a similar problem wherein they can connect as themselves, but not as a super user unless they have reset the libbath?

To be honest having tried whatever I can think of I haven't a clue!

I'd be grateful if anyone could suggest even the most outlandish resolution. Thanks Kev
