I have been building R-devel daily for years. In the last week or so, R-devel has failed make check with the error in   tests/Examples/parallel-Ex.R

The specific error is
> pkgname <- "parallel"
> source(file.path(R.home("share"), "R", "examples-header.R"))
> options(warn = 1)
> library('parallel')
Error in dyn.load(file, DLLpath = DLLpath, ...) :   unable to load shared object
'/hpscc/usr/local/gcc-4.1.2/build/R/R-devel-build/library/parallel/libs/parallel.so':   /hpscc/usr/local/gcc-4.1.2/build/R/R-devel-build/library/parallel/libs/parallel.so: undefined symbol: CPU_COUNT
Error: package/namespace load failed for ‘parallel’ Execution halted
