[Mono-dev] Using SslStream

[Richter]

I have read that document. It references a makecert utility which is nowhere
to be found on my system. I am running Debian "Squeeze" (testing
version) and installed the latest available mono-complete package from the
Synaptic Package Manager. The version number for the mono packages is 2.4.4.
Is there a newer mono release that includes this utility or should it have
been packaged with 2.4.4?
