Copy the bash completion script that comes with tig to
$out/etc/bash_completion.d/.
Note: to enable bash completion in NixOS, set
environment.enableBashCompletion = true;
The build complains about missing "file" and "which" commands, so add them as
build inputs.
"file" is used by the autotools configure script to tweak what -m flag
(if any) to pass to the linker when it asks it for shared library
support.
Here is an example of -m values for GNU ld:
Supported emulations:
elf_x86_64
elf32_x86_64
elf_i386
i386linux
elf_l1om
elf_k1om
"which" is used in the build phase to look for svnversion and git, to build a
version stamp. Since we build from a release tarball (and don't pass svn or git
as inputs either), this check fails and falls back to the version number in the
tarball.
There is one build warning left, but I think this is normal on NixOS:
/tmp/nix-build-lighttpd-1.4.32.drv-0/lighttpd-1.4.32/libtool: line 1085: ldconfig: command not found
One important denial of service (in 1.4.31) fix: CVE-2012-5533[1].
NOTE: There are some errors about missing commands during the build, but
I'm pretty sure they were there before. And the result seems to be
working anyway...
* /usr/bin/file: No such file or directory
* /bin/sh: line 2: which: command not found
* /tmp/nix-build-lighttpd-1.4.32.drv-0/lighttpd-1.4.32/libtool: line 1085: ldconfig: command not found

It's quite amazing that we've managed to pass incorrectly spelled command line
flags to Cabal for ages without ever noticing. :-)
The search path options --extra-{include,lib}-dirs are usually unnecessary,
because the build environment is set up such that gcc and ld find those headers
and libraries automatically, i.e. without needing extra flags. The bubble burst
on MacOS X, though, where the build of haskell-text-icu couldn't find the icu
library without manually setting DYLD_LIBRARY_PATH in that build. Fortunately,
cabal takes care of that issue if a correctly spelled --extra-lib-dirs flag is
passed.
