Dear Phil,
In order to specify a particular blas library, you have to use the option --with-blas of the configure shell (--with-blas=/System/Library/Frameworks/Accelerate.framework/Versions/A/Frameworks/vecLib.framework/Versions/A/libBLAS.dylib in your case). Superlu is the default linear solver. There is a version along the getfem package. If you use --enable-superlu=no this will disable the version distributed along with getfem and then Superlu will be searched on your system. Yves.
