[gdal-dev] vsicurl and HDF5

[Joe Lee]

Hi, Paolo!

I tested on mac:

Darwin nene.ad.hdfgroup.org 21.6.0 Darwin Kernel Version 21.6.0: Sun Nov  6 23:31:16 PST 2022; root:xnu-8020.240.14~1/RELEASE_X86_64 x86_64

I’m using `brew install gdal.`

I just tested with 3.6.2 and also worked fine. ☺
I hope it works on your Mac too!

Thanks Even!
I just tried with the osgeo GDAL container, and it is working, many thanks!
Previously I tried to run it from OSX, and I got that error.

Thanks also to Joe for testing that :)
