Maciek,

Ah, I see.  Some configure targets, when given an explicit path, just
"trust" that the libraries are there and add them to the library list.
 I suspect
what is happening is that the --with-netcdf code isn't checking that 
/usr/local is ok, and instead the libraries are added to the lib list.  Then
when it tries to link with the hdf libraries the link fails because the netcdf
libs aren't found. 

I can see that this is a confusing effect, but I am not inclined to do anything
about it.   Was there a particular reason you were telling configure to 
use netcdf from /usr/local when you knew it wasn't there?

Yes.
