My code ended up being the following, which works perfectly.

sub get_depend {
  my $ebuildfname = shift;
  my $ebuildcontents;
  my %ebuildvars;
  my $pkgname = $ebuildfname;

  $pkgname =~ s|/usr/portage/||;
  $pkgname =~ s|(.+)/.+/(.+).ebuild|$1/$2|;
  my $pkg = parse_package_name($pkgname);
  $pkg->{version} =~ s/^-//;
  $ebuildvars{PV} = "$pkg->{version}$pkg->{suffix}";

  open EBUILD, "< $ebuildfname" or die "Couldn't open '$ebuildfname' t
+o get DEPEND\n";
  while(<EBUILD>) {
    if(/^\s*if\s*/ || /^\s*#/) {
      next;
    }
    if(/^\s*\w+\(\)\s*{\s*$/) {
      last;
    }
    $ebuildcontents .= $_;
  }
  close EBUILD;

  while($ebuildcontents =~ /\b([-A-Z0-9_]+)\s*=\s*\"(.*?)\"/sgc) {
    my ($varname, $varvalue) = ($1, $2);
    $varvalue =~ s/\$\{?(\w+)\}?/$ebuildvars{$1}/gs;
    $ebuildvars{$varname} = $varvalue;
  }

  my $depend = $ebuildvars{'DEPEND'} || '';
  $depend .= " $ebuildvars{'RDEPEND'}" if(defined $ebuildvars{'RDEPEND
+'});
  $depend =~ s/(\s+|\n+)/ /gs;

  return $depend;
}
