[udunits] problem with utopen & -ludunits

I'm trying to run the configure script to install MRG CDFconvert: 
http://www.atmos.albany.edu/facstaff/rmctc/cdf_cvt/

I've attached a version of configure sh script with the log of running it.  I'm
writing because I keep getting the following error:

"checking for udunits... /usr/bin/udunits
checking for utopen in -ludunits... no
configure: error: Udunits library not found - possibly an incomplete udunits
build?  Rebuild the
        udunits package and try again."

I keep getting an error regarding udunits, though you can see in the previous 
line that
udunits is installed.  I've rebuilt udunits and gotten the same results.  I've 
tried using EXTRALIBS and gotten nowhere. 


As I understand it, utopen is a function call that opens units files, right?  
But I'm not quite sure what -ludunits defines.

I've attached the configure script and log file.  Thanks!


Below is the code where the error occurs:
