Package: r-base-core
Version: 2.11.0~20100402-1
Severity: normal
Hi,
r-base-core includes an embedded copy of the File::Copy::Recursive Perl
module in /usr/share/R/share/perl/File/Copy/Recursive.pm. The package
libfile-copy-recursive-perl includes a newer version of this library.
Please consider using this package instead of included a copy.
Regards,
Ansgar

Ansgar,
Thanks for the four bug reports about the inclusion of Text::DelimMatch and
File::Copy::Recursive in R (and hence Ra, a patched version of R).
GNU R is a fairly large and complex software system that I have been
maintaining (or co-maintaing) for close to a decade. There is very good
understanding between upstream and Debian about trying not to patch R to make
it differ from other installations. R installs almost all of its code below
/usr/lib/R (and bits below /usr/share/R) which allows it to perform
identically on various OSs and by extension, Linux distributions. Configure
et al are used to employ binary libraries, but that is not done for
Perl. These small modules are simply included. This is entirely defensible.
So in this case, among the 26mb (installed) of the base R we do fine two
doubled-up Perl packages -- which I find entirely acceptable given that there
is no configure infrastructure to test for them. Plus, more and more of the R
infrastructure itself is move from Perl to R itself (as has already happened
for the help parser) so this may well be on its way out.
I'd be happy to introduce you to the upstream team (CCing one member) if you
wanted to discuss inclusion of newer versions there.
Regards, Dirk
