Comment(by takeshi@…):

 I agree with you. I prefer Accelerate.framework that comes with Mac OS X.

 atlas has been the default for a while in various ports to avoid the
 problem of CDOTC CDOTU ZDOTC and ZDOTU in BLAS (see
 [http://developer.apple.com/hardwaredrivers/ve/errata.html#fortran_conventions
 Accelerate.framework errata] with g95 and 64-bit gfortran. Using wrappers
 is a workaround to this problem. I wrote
 [https://github.com/tenomoto/dotwrp dotwrp] and dotwrp port.

 In fact arpack does not seem to use CDOTC CDOTU ZDOTC and ZDOTU so there
 is no problem to use accelerate variant as a default.

 I attach another patch for accelerate as the default. It is your choice.
 (Or should we discuss this in MacPorts Development ML?)
