Two issues spring to mind when I read the comments below.

 # 3. Send the installed version to the Repository for checking.

    my $res = $pkg->uptodate($target);
    unless ($res->ok) {
    return Error("bundled package - no upgrade available")
      if $bundled;
    return $res;
    }
    my ($uptodate, $newversion) = $res->result_l;

    # 4. Return uptodate(t/f), newversion, oldversion, bundled(t/f):
    return List($uptodate, $bundled, $precious, $newversion, $ver_p);
}

sub uptodate {
    my $o = shift;
    my $target = PPM::UI::get_targ(shift)->result;
    my $desc = $o->describe($target);
    if ($o->{current_rep} and $desc and $desc->ok) {
    my $u2d = $o->{current_rep}->uptodate(
        $target,
        $o->{id},
        $desc->result->version_osd,
    );
    return $u2d;
    }
    Error("package $o->{rawname} not found in repositories");

I see the same problem. One pattern that emerges is the following. The ppm utility comes configured with two ActiveState repositories: "ActiveState PPM2 Repository" and "Activestate Package Repository". The problem seems to lie in whether or not a given package is in one or both repositories:

• for a package like Module-Which, which is in both repositories, installing the latest version and then querying whether or not an upgrade is available results in the package being reported as up-to-date.
• for a package like CGI-Enurl, which is in the "ActiveState PPM2 Repository" only, installing the latest version and then querying whether or not an upgrade is available results in an upgrade reported as being available from the "Activestate Package Repository", even though, as you found, the upgraded version matches the installed version.

As a poor workaround, if within the ppm shell you turn off the "Activestate Package Repository" using the rep off command, then, for example, CGI-Enurl would be reported as up-to-date. However, there may be packages within the "Activestate Package Repository" that are not in the "ActiveState PPM2 Repository", so doing this may result in some available packages not being found. As well, searches may be slower without the "Activestate Package Repository", as this uses a database lookup.

There's a ppm mailing list available which would be a good forum to report this (it's a low-volume list, and ActiveState developers regularly monitor it).

CGI-Enurl is in both repositories however one is linux and one is windows.

For some reason it appears that PPM is always checking "ActiveState Package Repository" first or giving it priority. Turning off that repository causes the correct results to be reported.

My list of repositories in the ppm utility only includes those for MSWin32-x86-multi-thread-5.8, which is why I don't find a CGI-Enurl package in the "ActiveState Package Repository" repository.
