It seems like your exec is in perpetual looping for some reason. I didn't have time to look at it too much but if you do the following, it runs through once and exits out of the BEGIN loop.

Change: 
exec 'env', $^X, $0, @ARGV;

to: 
exec 'env', $^X, $0, @ARGV if 0;

[download]
After that loops once, $ENV{'LD_LIBRARYN32_PATH'} will be populated with what you need.
Edit: added proper breaks and such because I was an idiot yesterday and forgot how to format!
