[Rd] Problem with creating default NAMESPACE on FreeBSD

After building and installing R-devel from 21/07/2011 on FreeBSD 9.0-CURRENT
(amd64), starting R gives the following warning:

Beim Start - Warnmeldung:
package 'datasets' in options("defaultPackages") was not found

This happens with all versions after 14/07/2011. I think it is related to

CHANGES IN R-devel PACKAGE INSTALLATION
Packages without explicit ?NAMESPACE? files will have a default one created
at build or INSTALL time, so all packages will have namespaces. A consequence
of this is that ?.First.lib? functions need to be renamed, usually as
?.onLoad? but sometimes as ?.onAttach?.


Package 'datasets' seems to be installed correctly under
/usr/local/lib/R/library/:

ls -l datasets/
total 18

Calling options("defaultPackages") shows all relevant packages:

$defaultPackages
[1] "datasets" "utils" "grDevices" "graphics" "stats" "methods"


But trying to load library 'datasets' fails with the following message:

library(datasets)
Fehler in library(datasets) :
package 'datasets' does not have a NAMESPACE and should be re-installed


Googling around for some days now it looks like this does not happen to
anyone else (at least there are no infos). Does anybody knows what is going
on here?

Any help would be appreciated,
Rainer Hurling

It does not seem to happen to anyone else, including me on FreeBSD. Is this a
completely clean install? src/library/datasets/Makefile definitely installs
a NAMESPACE file as part of the mkR1 target, so I would check that you have a
src/library/datasets/NAMESPACE file in your sources.

(There was a short window on the 16th when it happened as a commit for
src/library/datasets/NAMESPACE was missed at first.)

One possibility is that you are building from a tarball snapshot without
mentioning it, and the (unspecified) tarball is incomplete.

For R-devel using tarballs is not a wise idea: they are really only
checked carefully in pre-release periods. (One of the checks is that
AFAIR CRAN builds from the tarballs, but CRAN is not manned at present.)

But as far as I can the 'make dist' procedure does work now and did at
some point in the last week.
