mosh: add missing dependency on openssl

[neverpanic (Clemens Lang)]

Mosh failed to build on our buildbots (​http://build.macports.org/builders/buildports-lion-x86_64/builds/5369).

checking for OPENSSL... no
configure: error: Package requirements (openssl) were not met:

No package 'openssl' found 

Consider adjusting the PKG_CONFIG_PATH environment variable if you
installed software in a non-standard prefix.

Alternatively, you may set the environment variables OPENSSL_CFLAGS
and OPENSSL_LIBS to avoid the need to call pkg-config.
See the pkg-config man page for more details.

It seems the mosh port is missing a dependency on openssl. I'm attaching a patch that fixes this.

Sorry about that - the latest version added the dependency, but I didn't notice because my system already had openssl installed. This patch LGTM.

Is there a way I can test building packages in a clean environment without waiting for the buildbots?

[neverpanic (Clemens Lang)]

Commited in r99015.

Unfortunately, there's no good way to test in a clean env at the moment. You could try a separate installation of MacPorts with a different prefix, though. Section 2.3.2 of the guide has more on that.

The best way to do this is trace mode (-t), which provides a poor man's sandbox hiding all files that were not installed by a dependency. Unfortunately, it is currently broken (but I am working on fixing it).
