Comment (by olly):

 FreeBSD also seems to use `DYLD_LIBRARY_PATH`
 (https://www.freebsd.org/cgi/man.cgi?query=dyld&apropos=0&sektion=0&manpath=Darwin+8.0.1%2Fppc&format=html)
 so setting it to an empty value is potentially problematic.

 Can we not just make the code to set and export `DYLD_LIBRARY_PATH`
 conditionally - something like:

 {{{
 #!sh
 if [ -n "INTREE_DYLD_PATH" ] ; then
   DYLD_LIBRARY_PATH=$INTREE_DYLD_PATH
   export DYLD_LIBRARY_PATH
 fi
 }}}

 `App::Prove` is documented as ''"Implements the "prove" command"'' and
 ''"The "prove" command is a minimal wrapper around an instance of this
 module"'', so it seems a safe approach.

 `export foo=bar` is actually
 [http://pubs.opengroup.org/onlinepubs/009696799/utilities/export.html
 specified by POSIX], but it's not portable to older shells - the autoconf
 manual notes:

 > Posix requires 'export' to honor assignments made as arguments, but
 older shells do not support this, including '/bin/sh' in Solaris 10.

 And Solaris 10 is
 [https://en.wikipedia.org/wiki/Solaris_%28operating_system%29#Version_history
 apparently still in support for] another 5 years.
