p4: No such file or directory - when in reality it exists

I have installed p4 command line client on the server, and something strange is happening. It exists, has executable rights, but I cannot execute it because I received an error message that it does not exists.

I tried looking around, and everyone else who had this problem realized they picked the wrong binary for their box, but I made 100% sure I didn't.

the /usr/local/bin/p4 file is:

• 0x0755
• in my $PATH directory (/usr/local/bin)
• exists in the correct place
• execution attempted as root & as ubuntu users

here is my terminal output:

ubuntu@ubuntu:~$ sudo su
+ sudo su
