I ment must as in the only way to get the right result. But I have to correct myself (below). > The bug filed against the package suggests "libopenmpi-dev | lam4-dev". > Will this be a problem? The an installed lam4-dev would suffice even on systems that need libopenmpi-dev. Doesn't work. >> Further you have the choice of creating libhypre-dev-common containing >> the shared files.
