Comment (by chadcatlett):

 I had a few chances today to dig into why lftp wasn't compiling on my
 machine.

 Specifically I dug into needtrio.m4 that comes with lftp's tarball. I've
 uploaded the relevant config.log section to http://xx0r.net/mp-lftp-4.9.2
 -config_log-snippet.txt as well as attached here.

 In the logfile it shows the error being from `"-Werror=implicit-function-
 declaration"`.

 If the autoconf configure script determines that trio is needed it defines
 a C constant named `TRIO_REPLACE_STDIO` and sets the autoconf/automake
 variable `NEED_TRIO` to `yes *reason*`.

 It is referenced in `Makefile.am`
 [https://github.com/lavv17/lftp/blob/v4.9.2/Makefile.am#L4-L7 here], which
 tells the generated Makefile to build the code in the `trio` directory of
 the tarball.

 In `src/Makefile.am` it is referenced in a few places
 [https://github.com/lavv17/lftp/blob/v4.9.2/src/Makefile.am#L38-L40 here],
 [https://github.com/lavv17/lftp/blob/v4.9.2/src/Makefile.am#L79 here], and
 [https://github.com/lavv17/lftp/blob/v4.9.2/src/Makefile.am#L103 here].
 These usages set the bundled trio to be linked into the binary as well as
 setting up the include path to include the bundled trio's directory.

 So that sets things up for failure in terms of if trio is needed or not.

 There is another unrelated issue with lftp that is related to the bundled
 trio itself, which is that it is using C++ headers in a C file which is a
 big no-no.
