I build all packages some time ago with binutils-gold and your package build
without an hard failure, but I noticed that you seems to provide a library in
a specific library package so other packages can link against it without
problems.... but your shared object has still some unresolved symbols which
the program which links agaomst it must resolve. This isnt a good idea because
when you introduce new dependencies the package previously linked against the
old version will break because it doesnt know about the new dependency.
Maybe you could link against all needed libraries so programs must not link
against libraries which it doesnt need to use.
Maybe it is related to following bugs which hard failed due to unresolved
symbols in programs

This is similar to the 'gsl + gslcblas' issue -- pgapack uses MPI
implementations, here libopenmpi1 (and libm I suppose).
The problem, if any, is with Open MPI upstream where symbols are now split
over distinct libraries libopen-rte, libopen-pal and libmpi_$lang.so.
This was discussed a few times on the Open MPI upstream list, but I forget
the reasoning. I think this can be closed.
