Make Errors

I successfully compile on ubuntu, but when I run make I receive the following error: 

home/GSI1/comGSIv3.7_EnKFv1.3/src/obsmod.F90:1221:4:

 1221 | use file_utility, only : get_lun
      |    1
Fatal Error: Cannot open module file ‘file_utility.mod’ for reading at (1): No such file or directory
compilation terminated.
 

Any thoughts?
