w3m is a text browser. I use it a lot if I need to test stuff. Recently, I got an email saying that Emacs Wiki had an invalid certificate. Everything seemed to be fine, however. But a few minutes ago, I tried to run `w3m https://www.emacswiki.org/` from my Terminal (OSX El Capitan) and got an SSL error.
alex@Megabombus:~$ w3m -dump_extra https://www.emacswiki.org/ SSL error: error:00000000:lib(0):func(0):reason(0) w3m: Can't load https://www.emacswiki.org/.
Thanks to twb on #emacs, I found the problem. He said: “What’s `ldd` called on OS X? Find out if `w3m` is using `gnutls` or `openssl`.” The equivalent to ldd on OSX is `otool -L`.
As it turns out, a simple reinstall switched from libssl 0.9.8 to 1.0.0 and now it works.
