We never really know how good popcon works. I havn't found any rdepends for jblas and it does not ring a bell in connection with some Debian Med package. However, BLAS in general was discussed on Debian Science several times - not sure about tha Java implementation. > And if we do update in Debian, I thought readers of this list might have > opinions about whether I should switch the Debian packaging from > building against lapack to openblas. As far as I know (which is not much!) we should favour openblas. Kind regards Andreas. -- http://fam-tille.de
