You should probably add __i386__ to the define tests here.

No - the GDAL HDF4 driver is expecting the v2 name.

It's a hobby for me.  And all I can offer is what I've found that  
works for me, I don't know if poking around in your setup will help.

Note: I've been *slowly* updating my build instructions on my site,  
but I haven't gotten to the GIS stuff yet.  Here's a quick-n-dirty  
summary of the relevant bits to your problem (assuming everything  
needed in /usr/local, otherwise a lot of --with options needed):

- netcdf

./configure --disable-f77 --disable-cxx --disable-examples --disable- 
dependency-tracking --disable-utilities

- HDF4 4.2r2

hconv.h: apply the endian patch

./configure --disable-fortran --disable-dependency-tracking --disable- 
netcdf

- GDAL (fill in other options you need):

./configure --with-threads --without-grass --with-netcdf=/usr/local -- 
with-hdf4=/usr/local
