I guess this will tell you something:

The response (I guess) is "No" to the HTTP question and "Yes, but probably in 
a too old version" to the libcurl question.

I seem to recall an earlier request to install some HTTP package, some 
version. And, it is not to be difficult or anything that I do not usually 
comply with these requests immediately, it is simply that I have found it 
interesting and useful to observe, well, what happens if I don't do that, 
what is the error reaction from the builder? And sometimes, as in this case, 
we find some weakness, perhaps it is in Cabal (I mean, what do you think of 
an error message that says "Setup: Package darcs-2.2.0 can't be built on this 
system.", but no additional details provided?), perhaps it is somewhere else.

In any case, I got an error message from a build that complained about the 
HTTP package (and also about network)

but the very next build passed the configure step, so the (tentative, of 
course) conclusion in this case was that the HTTP/network complaint was 
needless. In any case, I still haven't complied with the HTTP/network 
request.

I'll stop here, there is more in the reply to Petr's reply to this letter.
