Here, $interpreter is e.g. /usr/bin/perl5.8.8, and, unlike
ExtUtils::MM_Unix::fixin(), this yields shebang line specific
to the installed perl version, which is rather undesired.

Perhaps $Config{startperl} should be used instead.
$ perl -le 'print $^X'
/usr/bin/perl5.8.8
$ perl -le 'use Config; print $Config{startperl}'
#!/usr/bin/perl
