[Rd] R libcurl does not recognize server certs

[Roman, John]

Dirk,
ive changed the subject given the nature of the present debugging.  Im aware i can extend extras from download.file to install.packages however
im curious to know why libcurl in the R invocation does not honor the CA bundle on my system.

how would I pass a CA bundle to install.packages?  the function has numerous arguments before the extras are taken.

See 'help(download.file)' -- it's a little hidden but you can just make the
external curl (which, as you say, works in your particular circumstances) the
default for remote file access from R too.

Next time please try to be a little more specific with your questions and
their subject line.  Methinks nothing here has anything to do with the httpd
server you employ.
