No libnetcdff.a file is generated becasue you didn't specify wither of the
configure options --enable-shared or --enable-separate-fortran (which would
be turned on automatically if shared libraries were built).  So your build
should have put the Fortran API into the libnetcdf.a library that was installed.

I just checked this by building from 4.1.1 the way you did, and no libnetcdff.a
was installed, just libnetcdf.a and libnetcdf.la, but gfortran still built f90
programs OK:

  $ FC=gfortran ./configure --disable-netcdf-4 --prefix=/machine/russ/nc411
  $ make check install
   ...
  test$ cp ../netcdf-4.1.1/examples/F90/simple_xy_wr.f90 .
  test$ /machine/russ/nc411/bin/nc-config --fflags
  -g -O2 -I/machine/russ/nc411/include
  test$ /machine/russ/nc411/bin/nc-config --flibs
  -L/machine/russ/nc411/lib -lnetcdf -lcurl
  test$ gfortran -g -O2 -I/machine/russ/nc411/include simple_xy_wr.f90 -o 
simple_xy_wr -L/machine/russ/nc411/lib -lnetcdf -lcurl
  test$ ./simple_xy_wr
   *** SUCCESS writing example file simple_xy.nc! 

So I can't reproduce the problem you are seeing.  Maybe you have a previous 
installation with older shared libraries, and those are being used instead of
the new static library you just installed?

I doubt is this is a version issue, but here are the versions of compiler and 
OS 
I'm using:

  test$ gfortran --version
  GNU Fortran (GCC) 4.2.1 (Apple Inc. build 5659) + GF 4.2.4
  test$ cc --version
  i686-apple-darwin10-gcc-4.2.1 (GCC) 4.2.1 (Apple Inc. build 5664)
  test$ uname -a
  Darwin mort.unidata.ucar.edu 10.4.0 Darwin Kernel Version 10.4.0: Fri Apr 23 
18:28:53 PDT 2010; root:xnu-1504.7.4~1/RELEASE_I386 i386
