Subject: [Rd] R-devel no longer supports Ubuntu 14.04 LTS (insufficient
 PCRE version)

I think you have it backwards: Ubuntu 14.04 does not support R-devel ....

PCRE 8.32 is 3 years old, so Ubuntu 14.04 shipped an already quite old 
version 19 months ago.

R has long said that its requirement was

    PCRE (version 8.10 or later, preferably 8.32 or later)

and 8.32 is indeed preferable: the aim is that all the current PCRE 
regex syntax be usable on all platforms.

Given that you appear to be installing R from the sources, PCRE is no 
more difficult to install from source ....

R-devel is 'under development' and months off release: if this proves to 
be too restrictive we can postpone the aim to 3.4.x.
