system('unset LIBPATH'); doesn't work since unset is a shell command, not a program.

system(q{sh -c 'unset LIBPATH'}); would run the shell command, but it would uselessly change the environment of a shell that exits immediately afterwards.

You want to change the current process's environment. delete $ENV{LIBPATH}; is the way to go. If it doesn't work, maybe because it's being done too late. Try putting it in a BEGIN {} block as near the top of your script as you can.
