Right, I neglected to mention that I also tried to edit configure to link against atlas, cblas, f77blas, etc. to the same effect about the hidden symbol.
Are you saying that all I need to do is define LAPACK_LIBS as such and then run configure, or do I still need the with-lapack-prefix as well?? I tried the former, and it fails to build, saying it can't find lblas (I changed back to the original configure file).
|16 $ echo $LAPACK_LIBS
-L/home/skipper/built/atlas_files/lib -llapack -lf77blas -lcblas -latlas
What look to be the relevant lines in config.log are now something like
gcc -o conftest -I./lib/src -msse2 -g -O2 conftest.c -L/usr/lib -llapack -lblas -lgfortran -lc -lc -lm
