Max,

can you send me the detail about you setup, please? (most importantly  
OS X version and platform). Also quite helpful would be the last page  
of the confgure output.

The error above looks familiar from times when BLAS parameters had to  
be specified at configure time. Depending on your cctools, you may  
not be able to use the new system, so possibly you have to use  ./ 
configure  --with-blas='-framework vecLib' --with-lapack

Cheers,
Simon
