Hi Jennifer,

Thanks for continuing to respond.

It's not that mysterious why it doesn't work - the libdap API has
apparently changed.  The gadods sources are trying to load header
files from libdap that don't exist in libdap 3.5.2.

Ok, but what version of libdap /does/ work with this libgadods?  What
are the version numbers for the libraries currently distributed
through supplibs?  I think it would be nice if this information was
included in a README in the supplibs downloads, along with URLs for
the original source distributions.

The list I have so far is the following:
(These are the current version numbers.  I know that in some cases
earlier versions must actually be required.)

HDF 4.2r1
gadods
libdap 3.5.2
libnc-dap 3.5.2
netcdf 3.6.0-p1
libwww 5.4.0
rx 1.5
udunits 1.12.4
readline 5.0.005
zlib 1.2.3
gd 1.8.4
libpng 1.2.8_2
jpeg 6b


Thanks,

Tom
