[Rd] make error in R devel

[Gavin Simpson]

Dear list,

I just hit an error that stopped my make && make check-devel operation 
on my linux box (FC3, i686 P4 2GB RAM). Just to note that I've been 
building the development branch(?) for some time and this is the first 
hint of a problem.

1) updated the src tree using svn update
2) ran ../configure --with-recommended-package=no from my build directory
3) got:
R is now configured for i686-pc-linux-gnu

   Source directory:          ../src
   Installation directory:    /usr/local

   C compiler:                gcc  -O3 -g -march=i386 -mcpu=i686
   C++ compiler:              g++  -O3 -g -march=i386 -mcpu=i686
   Fortran compiler:          g77  -O3 -g -march=i386 -mcpu=i686

   Interfaces supported:      X11, tcltk
   External libraries:        readline, BLAS(generic)
   Additional capabilities:   PNG, JPEG, iconv, MBCS, NLS
   Options enabled:           R profiling

   Recommended packages:      no

Note I've editted config.site to compile with optimisations -O3
4) did make && make check-devel and get this:

5) Looking at stats-Ex.Rout.fail I see this at the end:

Error in loadNamespace(name) : there is no package called 'MASS'

But as there are no recommended packages this fails as indicated. So is 
there something wrong with what I'm doing (i.e. something recent in the 
last week has changed that I missed in NEWS) or is this a bug in the 
tests or examples?

Cheers
