  I am painfully aware that this is most likely a problem with my
system, but I am nevertheless going to ask if anyone has any
ideas/suggestions for diagnosis and trouble-shooting.

- From a clean checkout of release 66624 on Ubuntu 12.04 (32-bit, sorry!):
gcc (Ubuntu/Linaro 4.6.4-1ubuntu1~12.04) 4.6.4

svn checkout https://svn.r-project.org/R/trunk/
tools/rsync-recommended

cd ../r-build
../r-devel/configure

R is now configured for i686-pc-linux-gnu

  Source directory:          ../r-devel
  Installation directory:    /usr/local

  C compiler:                gcc -std=gnu99  -g -O2
  Fortran 77 compiler:       gfortran  -g -O2

  C++ compiler:              g++  -g -O2
  C++ 11 compiler:           g++  -std=c++0x -g -O2
  Fortran 90/95 compiler:    gfortran -g -O2
  Obj-C compiler:	

  Interfaces supported:      X11, tcltk
  External libraries:        readline, lzma
  Additional capabilities:   PNG, JPEG, TIFF, NLS, cairo
  Options enabled:           shared BLAS, R profiling

  Capabilities skipped:      ICU
  Options not enabled:       memory profiling

make fails at:

byte-compiling 'methods'
initializing class and method definitions ...Error: .onLoad failed in
loadNamespace() for 'methods', details:
  call: new("classRepresentation")
  error: could not find function "isVirtualClass"

The only other oddity of my system/potential clue is that symbolic
links sometimes behave strangely because I am working on a VirtualBox
virtual machine with a virtual Linux filesystem layered over an HGFS
filesystem.
