[PC-BSD Testing] PBI launch bug found in PC-BSD 7.0 Beta 1

[Lawrence Sayre]

Whenever I try to install software using PBI's, all I get is the 
following message
 (wherein I have substituted "username" for my login name):

Command '/home/username/.PBItmp/.pbistart' not found.

Interestingly enough, the file that can't be found (.pbistart) is in
fact there. Here is its content:

#!/bin/sh
. /PCBSD/LANGS/PCBSDLANG
LD_LIBRARY_PATH=/Programs/.libs/ ; export LD_LIBRARY_PATH
cd /home/username/.PBItmp
./PBI
