I guess the simplest way is then to be explicit about what you want to happen, instead of hoping for some magic in Perl that you don't know about:

my $pattern = 'mc-lang-+([^-])-+([^-])*.rpm';
my $results = `$ENV{SHELL} -c echo $pattern`;

assuming that by $SHELL you mean the environment variable $SHELL and not the Perl variable $SHELL.
