+  28 Jun 2008; Markus Dittrich <markusle@gentoo.org> meep-0.10.1.ebuild:
+  Since blas-reference seems to result in a faulty meep, let's depend
+  explicitly on blas-atlas and add a warning in case the user has 
+  selected blas-reference (see bug #229693). Thanks much to 
+  Dustin Surawicz for tracking this down.
