dvm crash

[userxfce]

The following throws an exception instead informing that dmd has to be installed first.

./dvm-0.4.3-linux-debian7-x86_64 use

Idem, with help:

Of course, dvm --help works correctly

Yeah, I know the error handling could be a bit better. It doesn't actually crash, it's designed to just bailout if something goes wrong. But printing the stacktrace might not be necessary.
