Error compiling ARWpost Ubuntu

Dear all
I've got a problem that seems similar to other posts here but for the life of me I can't figure out a solution based on previous posts. I have successfully compiled and run WPS and WRF but when it comes to ARWpost I get this error when compiling.
module_interp.f:(.text+0xc429): undefined reference to `nf_inq_varid_'
module_interp.f:(.text+0xc5af): undefined reference to `nf_inq_varid_'
module_interp.f:(.text+0xc67d): undefined reference to `nf_inq_var_'
module_interp.f:(.text+0xc95a): undefined reference to `ncvgt_'
module_interp.f:(.text+0xcca7): undefined reference to `ncvgt_'
module_interp.f:(.text+0xcf87): undefined reference to `ncvgt_'
make: [ARWpost.exe] Error 1 (ignored)
I have tried older versions of netcdf, no luck. I've tried the older version of ARWpost but that doesn't work either. I've tried with gfortran and intel fortran. I am working on Ubuntu 10.10. Please can anyone help, any suggestions welcome
best regards
Chris
