> The build system includes the script {{build_tools/list_valid_installed_externals}}, which collects all modules installed from Digium, like various audio-codecs and the Digium Phone Module for Asterisk (DPMA; res_digium_phone). Then, the Makefile double-checks the installed modules, whether an old module is still installed. If such an old module is found, {{make install}} prints a big warning.
> To be downloaded, those external modules required the shell _bash_. Therefore, it is okay that this script requires the shell _bash_ as well. However, when that shell is not installed, {{make install}} prints the following twice: {{env: bash: No such file or directory}}. This is because the script does not set the shell directly but finds _bash_ via the tool _env_. When the header of the script is changed to {{#!/bin/bash}}, the following is printed twice: {{gmake\[1\]: ./build_tools/list_valid_installed_externals: Command not found}}.
> To solve this, one approach is to avoid calling this script when the variable $\{BASH\} is not set. Another approach is to ignore any error of that script.
> This issue was introduced in August 2016 with commit [6caf6bc|https://github.com/asterisk/asterisk/commit/6caf6bcdad003237725bf458a26db8ff74120508]. Because that commit does not reference a Jira issue, I cannot link to a causing issue. Therefore, so the original author learns about this issue here, I have to invite him manually in the code review via Gerrit.
