application must be either 32 bit or 64 bit.

It appears that the link is being requested as 32bit ('cc -32' or 'cc -n32')
while the netcdf library was built as a 64 bit object ('cc -64' or just 'cc'
on this system).

So, you can rebuild IMSL as a 64 bit object and link with 'cc' or
you can rebuild libnetcdf.a as a 32 object and relink using 'cc -n32'.

To rebuild netcdf in 32 bit mode.
% make distclean
% setenv CC 'cc -n32'
% ./configure
% make
