OK, so I solved my compilation problem by passing the following
as the linker command (added -L-ldl and -L-lz):

dmd -of/home/craig/cloud/vibe-tiles/vibe
/home/craig/cloud/vibe-tiles/temp.o -L-levent_pthreads -L-levent
-L-lssl -L-ldl -L-lz -L-lcrypto -g

How the GCC linker decides which libraries I need to explicitly
specify is indeed a mystery to me.
