Re: For whom using WRAPIT in NCL 5.2.0 on Mac intel 10.6

Hi Mary,

Thanks for the information.

Here is my though:
Using "-m32" and "-m64" actually overwrite the variable "nbits" that defined early. So I think my uncommented part can
be deleted from WRAPIT.

For the people who have no permission to modify WRAPIT, "-m32" and "-m64" options together with "-L "
option are good choice.

For the people who have permission to modify, my way is better way. After changing once, don't need change it again.
(I don't want to put the whole path of gfortran library after WRAPIT each time :)
