 For what is worth, doing this in pure {{{sh}}} would not be much more
 complicated... I should have thought about this earlier :-)

 Indeed.  I have checked it without Perl being in the {{{PATH}}} and
 {{{configure}}} failed okay.  That is, although it did not find Perl when
 it tried to evaluate the expression, but it will say {{{configure: perl
 not found}}} -- and then at the check for Perl it will stop and display
 the corresponding error message ({{{You must install perl before you can
 continue...}}}).
