Package: libgsl0-dev
Version: 1.8-2
Severity: normal
When building a executbale which needs libgsl0 it fails to
build unless libblas-dev is also install, sinve libgsl0 refers to
fucntions in libblas.
So libgsl-dev should depend on libblas-dev.

No, I think that is not correct.
You may have overlooked the fact the GSL itself comes with a set of blas
functions in the library libgslcblas -- this gives the option of staying with
basic blas (eg using libgslcblas) or by using another blas library, optimised
(like Atlas) or not, via libblas.. See the example session below.
So with that I am closing the bug report. If you disagree feel free to
re-open but add a few lines explaining my think my analysis is faulty.
Cheers, Dirk
