Thank you all forum folks for the replies.  My use case for curl 
is simply HTTP/HTTPS, not libcurl specifically.  That said, I was 
making a best effort to not use external dependencies per my 
requirements.  My feeling is that a platform should provide needs 
for modern computing, and web is a part of that.  I hope this 
question "goes away" in the future and there becomes a modern 
library alternative to the std.net for http as standard part of 
phobos.

So a number of great responses here, and I am going to explore 
the export option as well as the http2 (from arsd) option.  John, 
I'll check out the tsv-utils build as well, your CI server set up 
looks really great.  I am very interested to learn the best 
practices of distribution of prebuilt D apps and libraries.
