Thanks for the input, removing that flag did not fix the problem 
unfortunately. I was using those flags because I had just copied an 
install script from our cluster's support staff. However, I was able to 
get everything working by compiling with gcc (though this may not be 
optimal). I believe there is an issue in the intel libraries on our 
cluster. Thanks for the help!
