You should try to search the forum first for the answer:
`require - Google Search’%3A+no+such+file+to+load±-+mkmf+(LoadError)+site%3Aruby-forum.com
Anyway, you need the ruby development packages. In ubuntu / debian its
named ruby1.8-dev (or ruby1.9-dev)

details. You may need configuration options.

So, I installed rubycurl, that being the listed package of greatest maturity, but no document I can find can seem to help me use it. Most of the stuff on line refers to curb or multi-curb it seems.

You could also use net/http which is part of the standar library and documented:

Yes, but I am trying to move from using curl on shell to getting the same functionality without the two extra forks to shell and to curl itself. Plus the native has a bad wrap, I don't know if it's deserved, but I haven't found it copasetic myself.

Why two forks? In order to start curl as an external process you just
need one fork and one exec (or use "system"). Also, why do you say
"but"? Net/HTTP does not need "curl" or any other external process so
I do not see how my suggestion contradicts your goal. On the
contrary, I deliberately suggested to use Net/HTTP in order to _not_
have to depend on gems or external processes.

Among other things we have built the tool around curl facilities like the --trace-time function, and we don't want to mix in new stuff, or add variations in the kind of data we get. Also, all the switches for handling post data, HTTP headers, cookies, etc are working well, and it's not clear you can do all of those things, let alone in a reasonably good way, with the net/http. I am certainly interested in your opinion on that.
Curl registers timestamps for points before the socket connection, as well as for receipt of each of the important HTTP headers, and then after the HTTP protocol activities are over the closure steps. Can I get that from net/http?

Yes. Here's some pseudocode:
h = Net::HTTP.new
h.start do
p :connected!
h.request do |r|
p :headers!
r.read_body
p :body!
end
end

Yes. Here's some pseudocode:
I'm sorry. That is not pertinent to what I said. Perhaps you should learn curl.

You asked how to get timestamps using net/http for various things that curl gives timestamps for. The pseudocode I answered with below shows you exactly where to hook net/http to get those timestamps. I didn't think learning curl was required in order to get timestamps for various stages of an HTTP request using net/http. Perhaps you should be more specific in your requirements.
h = Net::HTTP.new
h.start do
p :connected!h.request do |r|
p :headers!
r.read_body
p :body!
end
end
PS: The Net::HTTP documentation explains how to do the following other things you asked if net/http can do in ruby-talk:363103, "handling post data, HTTP headers, cookies, etc"
