[Rd] Problem building package for R 2.10.0 on Mac OS X

[Prof Brian Ripley]

Please ask such questions on R-sig-mac, or directly to the Mac package 
builder (Simon Urbanek).

As you will see from

http://cran.r-project.org/web/checks/check_summary.html

at least 150 packages are in the same boat (not building because 
dependencies are missing), so something has gone wrong on the build 
machine.  There seem to be results for 'vegan', but they are for a 
pre-release (2.10.0 alpha), not the released version.

Perhaps related, there have been no R-patched builds on 
r.research.att.com for 'leopard' (the main R build for R 2.10.0) since 
Nov 4.

Simon has been travelling, and will no doubt get to this when he has 
time.  Meanwhile, Mac users can fairly easily build packages from the 
sources (provided they have installed Xcode), so this is not something 
to fret about.

One point specific to Mac is that the distributed packages are 
tri-architecture (i386, x86_64, ppc) and so need to work on all three 
archs to get distributed (at least in principle).  There have been 
quite a few packages (including earlier versions of yours) that failed 
on 64-bit platforms.
