Something may change in the build process. R wants this 'f77blas' library as it was encoded at configure time for R itself. My Debian testing box has [EMAIL PROTECTED]:~$ grep blas /etc/R/Makeconf BLAS_LIBS = -lblas [EMAIL PROTECTED]:~$ which is correct: 'blas' is library that can be provide by atlas (fast, big package) or refblas (smaller). My Ubuntu system (using our CRAN binaries for R) has [EMAIL PROTECTED]:~$ grep blas /etc/R/Makeconf BLAS_LIBS = -lf77blas -latlas [EMAIL PROTECTED]:~$ which is what you have, and which may have gotten there by accident. The odd bit is that I had autobuilds of Debian R packages fail on just one minor architecture (mips) for the same reason -- so maybe something changed at the atlas library / compiler intersection.
