No, it would not delay anything since I proposed to make those packages 
standard exactly when we upgrade R to the version which needs those 
packages.

The time should be NOW, unless review exhibits some snags...

This set of tickets is up for review again since about two weeks. in 
Trac#21770 , Jeroen Demeyer is of 
the opinion of keeping curl (and probably pcre, but he doesn't say that) as 
optional packages "for a while". This woulkd delay our already exceeding 
late upgrade of R by the same amount.

I am of the opinion that this upgrade is urgently needed (we are almost on 
year behind R), and I wouldn't like to see Sagematrh 7.6 getting out 
without it, or a good reason not to include it. I have ran it on my 
ptrivate branch for about 8 months, with no noticeable problems ; the 
delays were induced by the necessity of depending on an external SSL 
library (done since Trac#22189 

).

Questions :
What is your opinion ?
Should we hold a formal vote ?
Can you review this set of packages (I think that the two most important 
cases are Mac and Cygwin, both aving peculiarities) ?

Sincerely (and expectantly),
