Howdy Nicole!

Apparently something recently changed in Lahey fortran to cause this problem. 
This thread may help explain it:

http://www.laheyforum.com/showthread.php?t=10728

Certainly netcdf does not use the __divdi3 function directly. Presumably there 
is some mapping to 32 bit vs. 64 bit versions of these functions, and with 
Lahey's recent changes, something is going wring.

Unfortunately I do not have access to that version of the Lahey compiler. If 
you can use a previous version, that might be a good idea. 

Also you can try netCDF 3.6.2 (don't try the beta now, wait at least until 
beta4 comes out). It uses a different build system that may work better with 
Lahey.

I suspect the ultimate answer is to find out what library file on lahey 
contains this function and explicitly link to it...
