| | include solution for the record):
| |

Hey, I'm glad this solved your issue!

| | | Have you checked the time on the 
| | | laptop being correct and not set 
| | | to e.g. 1970-01-01 01:29?  In the 
| | | past, I have found ssl errors are 
| | | caused by the time being off on my 
| | | laptop, as in the case of a flat 
| | | cmos battery.
| | 
| | BTW - my clock and date are fine, 
| | the reason it works on some systems 
| | has to do with the SSL library being 
| | used, whether openSSL or libreSSL.  
| | And as I said,  similar happened to 
| | R itself for a very short time.  I 
| | can't find the references to the 
| | email exchange,  but Simon Urbanek 
| | gave a very nice explanation of why 
| | this was happening.  I also wonder 
| | whether it really is desirable to 
| | ignore an expired Cert in the Cert 
| | search path.  Not particularly 
| | knowledgeable on this,  but my 
| | offhand feeling is that could lead 
| | to problems.
| | 
| | Thanks again for the solution!

| Found it.  On June 9,  in the 
| R-developers mail-list,  a chain under 
| the topic "SSL certificate issues".

Perhaps it's this[*] one.  OpenSSL is 
really crusty and simply a mistake, thus 
I have heard, I hope LibreSSL or 
something else can replace it at some 
point, not just in MacOS and OpenBSD ... 

Best,
Rasmus
