I can only think of a few problems that would cause this error
message:

  - You haven't installed the netCDF library in the directory 
    /home/external/iitk/sachchidanandt/jish/model1/WRFV3/netcdf_links/lib

  - You installed the library there, but it is for a different library
    format or machine architecture than expected by mpif90, for
    example it is a 64-bit library but mpif90 requires 32-bit
    libraries, or vice versa

  - The link step should be done by the Fortran compiler you are using
    rather than "/usr/bin/ld".  Perhaps there was a script you needed
    to run before invoking mpif90 so that the right program would
    perform the link, rather than /usr/bin/ld?

This also may be a problem with your mpif90 installation rather than
netCDF.  Can you compile and link simple F90 programs with mpif90?

I recommend posing your question to the address@hidden mailing
list, as it may be wrf-specific.
