[ESS] wget/curl and DOWNLOAD make variable customization WAS: ESS 16.10 released

[Sparapani, Rodney]

To Martin: are you serious about “everyone” having R?  I don’t think you can assume that.
I often install ESS on systems that don’t have R.  We have many sites (ok 2 ;o) that could not
care less about R.  I do not want to have to install R just to install ESS.  And frankly, this
whole mess is created by julia support which I really do NOT care about at all.

To Martin and Vincent:  The answer is to customize the DOWNLOAD variable appropriately,
i.e. on Mac OS X I use DOWNLOAD = curl which you merely have to uncomment in Makeconf.

Excellent.
Thank you very much, Vincent, for providing them so nicely pre-packaged!

This comes from <ess>/Makeconf

DOWNLOAD = wget -O -

Since we rely on GNU makefile style anyway, we could replace the
above by smart if(.) constructions... But MacOS and Windows may
change again in the future ... (and Linux too, but there we find
that an replace 'wget ..' appropriately).

On the other hand, R has  download.file()  and "everybody" has
R, so we could think of replacing that by

   Rscript -e 'download.file(..........)'

and rely that R will be updated to keep download.file() always
working  ??

Hmm... I think this should be workable-around by a  wget switch?

(Well, 'make' is not perfect and even more our Makeconf/Makefile setup is not)

    > Both problems seem related to build system-specific instructions in the
ESS Makefiles.

*'Both'* ?  Which problem apart from 'wget -O -' not working
correctly on Mac and Windows?

Yes, very much, thank you, Vincent!
