Dear all, it seems there are some problems to install build-depends for the package vtk6_6.1.0+dfsg-4 on s390x [1]. It refuses to install libhdf5-openmpi-dev but does not try to install libhdf5-mpich-dev which is an alternative BD. The package builds fine on porterbox zelenka. What do I do wrong? Thanks [1] https://buildd.debian.org/status/logs.php?pkg=vtk6&ver=6.1.0%2Bdfsg-4&arch=s390x Anton
