I do not know what that option does. It seems to do something, but not
the right thing.
Actually, looking at texexec.rb I get the impression that --pages= is
not supported. One finds there

Could the --pages option made to work in texexec.rb? In texexec.pl I
find the following. I probably should learn ruby [and python for that
matter] ...

if ($Pages)  {
if ( lc $Pages eq odd ) {
print OPT \\chardef\\whichpagetoshipout=1\n;
} elsif ( lc $Pages eq even ) {
print OPT \\chardef\\whichpagetoshipout=2\n;

my @Pages = split( /\,/, $Pages );
$Pages = '';
foreach my $page (@Pages) {
if ( $page =~ /\:/ ) {
my ( $from, $to ) = split( /\:/, $page );
foreach ( my $i = $from ; $i = $to ; $i++ ) {
$Pages .= $i . ',';
}
} else {
$Pages .= $page . ',';

}
chop $Pages;
print OPT \\def\\pagestoshipout\{$Pages\}\n;

actually, the code is there ... scripts/context/ruby/tex.rb 

but there is a buglet in there: 

  opt  \\def\\pagestoshipout\{pagelist.join(',')\}\n;

should be: 

  opt  \\def\\pagestoshipout\{#{pagelist.join(',')}\}\n;

#{..} evaluates inside a string
