Why does the OpenSSL test fail with “bc: stack empty”?

On some DG/ux versions, bc seems to have a too small stack for calculations that the OpenSSL bntest throws at it. This gets triggered when you run the test suite (using “make test”). The message returned is “bc: stack empty”. The best way to deal with this is to find another implementation of bc and compile/install it. GNU bc (see http://www.gnu.org/software/software.html for download instructions) can be safely used, for example.
