Subject: [Rd] Outdated dependencies and install.packages()
Message-ID: <48ABF23B.70707@biostat.ku.dk>

This looks like a buglet:

> install.packages("lme4", depend=TRUE, lib="~/Rlibrary/")
--- Please select a CRAN mirror for use in this session ---
[...snip...]
** preparing package for lazy loading
Error: package 'Matrix' 0.999375-4 was found, but >= 0.999375.11 is
required by 'lme4'
Execution halted
ERROR: lazy loading failed for package 'lme4'
** Removing '/home/bs/pd/Rlibrary/lme4'
** Restoring previous '/home/bs/pd/Rlibrary/lme4'

and the DESCRIPTION file for lme 4 does have

Depends: methods, R(? 2.7.0), Matrix(? 0.999375-11), lattice
<http://cran.r-project.org/web/packages/lattice/index.html>


Looks like we're either not checking the version requirement of
dependencies, or something is making 4 > 11... (from my reading of the
code, it is the former, but I could have missed something).

We should at least document the behaviour.
