Hello James,

I'm the maintainer of the lapack-atlas slackbuild. Since this is a 
variation of Eugene's one I also don't link against blas (in my case 
atlas). Nevertheless I use several software packages compiled against 
lapack-atlas and never had a problem like yours. Moreover I definitely 
doubt that lapack should by any means provide a blas function. Thus I 
rather suppose that there is a problem with the way the Haskell library 
gets linked.

BTW, did you consider using ATLAS instead of the reference blas?

Best regards,

Serban Udrea
