| 
| The same thing happens with the current R patched.

| ========
| 
| - I have checked this with R-devel from 19 December and 26 December, as
|   well as with the current R patched (2013-12-27, r64562)
| 
| - Check fails when
| ls -l /usr/lib/libblas.so.3 /etc/alternatives/libblas.so.3
| lrwxrwxrwx 1 root root 29 Dec 28 10:31 /etc/alternatives/libblas.so.3 -> /usr/lib/libblas/libblas.so.3
| lrwxrwxrwx 1 root root 30 Oct  3  2012 /usr/lib/libblas.so.3 ->
| /etc/alternatives/libblas.so.3
| 
| - Version of libblas:
| libblas-dev    1.2.20110419 amd64 
| libblas3       1.2.20110419 amd64  
| 
| 
| - Check is OK when
| ls -l /usr/lib/libblas.so.3 /etc/alternatives/libblas.so.3
| lrwxrwxrwx 1 root root 38 Dec 28 11:04 /etc/alternatives/libblas.so.3 -> /usr/lib/atlas-base/atlas/libblas.so.3
| lrwxrwxrwx 1 root root 30 Jul 26  2012 /usr/lib/libblas.so.3 -> /etc/alternatives/libblas.so.3
| 
| - Version of libatlas
| libatlas3-base 3.10.1-2 
| 
| 
| (I also tried with openblas, and it worked just fine)
| 
| 
| - This happens in three different systems, one using gcc-4.7.2 (Debian
|   4.7.2-5) and two with 4.8.2 (Debian 4.8.2-1)
| 
| - I have configured and compiled R trying to follow debian/rules in the
|   r-base-core package. This is what I do:
| 
| ## with gcc-4.8 using -O3 or -O2 both lead to the check failure
| optimflags="-O2 -pipe -g"  
| export CC="gcc -std=gnu99"
| export CXX=g++
| export F77=gfortran
| export FC=gfortran
| export CFLAGS=$optimflags
| export CXXFLAGS=$optimflags
| export FFLAGS=$optimflags
| export FCFLAGS=$optimflags
| export LDFLAGS=-Wl,-O1
| 
| ./configure     --with-cairo  \
|  --with-jpeglib                      \
|  --with-readline                     \
|  --with-tcltk                        \
|  --with-system-bzlib                 \
|  --with-system-pcre                  \
|  --with-system-zlib                  \
|  --with-blas               \
|  --with-lapack             \
|  --enable-R-profiling     \
|  --enable-R-shlib         \
|  --build=x86_64-linux-gnu	  \
|  --with-tcl-config=/usr/lib/tcl8.5/tclConfig.sh \
|  --with-tk-config=/usr/lib/tk8.5/tkConfig.sh 
| 
| make -j8

I don't think it is a known issue. Can you isolate the actual test that
fails? How big is the actual discrepancy?  We should probably bring it to the
attention of the refblas maintainer.

You did what I do -- telling R to use external blas. In an ideal world the
resulting behaviour should be identical for all available BLAS implementations.
