BEGIN { my $self = $0; # or hardcode it, depending upon need if ( $ENV{'LD_LIBRARY_PATH'} !~ m|/path/you/want| ) { $ENV{'LD_LIBRARY_PATH'} = "/path/you/want:$ENV{LD_LIBRARY_PATH}" +; exec $self, @ARGV; } } use DBI;

    That's interesting! How does it get past the exec statement? In other words, what prevents the process from getting stuck in a loop?

      It checks if the new path is in LD_LIBRARY_PATH before running itself again. Once the new path is there, it doesn't run itself anymore, breaking the loop.

        It works, but I didn't get the stdout from a print statement inserted before the exec.

        Slimey, but satisfying.

        Thanks for the help.
