Hi,
Due to some security limitations, I've had to install DMD in my home
folder on one of my university computers.
When trying to build a basic vibe.d application (i.e., the one created
by dub init test --type=vibe.d), linking fails with a large number of
undefined references to functions in libssl, libcrypto, etc.
Running dub with -v shows that the command which is failing is:
dmd

If I then execute this command manually, with -v, then I can see that
this command is failing:

If I try to build the same project, initialised the same way, on a
machine with DMD and libssl, libevent, etc installed in a system-wide
location then everything works as expected. Does anyone know what I've
missed out when setting up DMD and the vibe.d dependencies?
Thanks,
Henry
Please post the error message, without it we're guessing.
