Yeah, I figured this out. I need to have HDF5 if I want NetCDF 4
format, but I couldn't get HDF5 to install on my computer. Anyway...

This is strange. Actually, both NetCDF 4.0.1 and NetCDF 4.1.1 work
just fine. In my simple script, I have the following
----
my $nc = PDL::NetCDF->new("data.nc", {REVERSE_DIMS => 1});
my $varlist = $nc->getvariablenames();
foreach my $var (@$varlist) {
print "\nVar: $var\n";
my $dims = $nc->getdimensionnames($var);
foreach my $dim (@$dims) {
my $dimsize = $nc->dimsize($dim);
print "$dim: $dimsize\n";
}
print "\n$var metadata\n";
foreach my $att (@$atts) {
my $attval = $nc->getatt($att, $var);
print "$att: $attval\n";
}
}
print $nc->info();
----
Everything works just fine until `print $nc->info()` when I get the
"Can't locate auto/PDL/NetCDF/info.al in @INC" error. Why am I not
able to load the NetCDF file as a piddle?
