>Description:
The package devel/pcre v6.4nb1 (from a pkgsrc tarball dated December 3, 03:35) 
will not build on a Cobalt Qube 2 due to duplicate trait definitions.
>How-To-Repeat:
cd /usr/pkgsrc/devel/pcre
make
>Fix:
Remove the #include <type_traits.h> lines from pcre_stringpiece.h.  The 
following patch fixes the build, but has not been tested on any other ports:
