Math::Calculus::Expression problem

[Sendu Bala]

I'm trying to install Math::Calculus::Expression and am coming across a
strange problem in CPAN.

First of all, 'install Math::Calculus::Expression' doesn't work for some
reason, because it can't be found (neither with 'i /Expression/').
Trying with the file path also fails in a bizarre way:

That's just really beyond me. Only root can then delete that tmp
directory. What's going on? (I've had no similar problem installing a
whole host of other modules via CPAN, including Bundle::CPAN)

Ah, the problem is that inside the tmp-16218 directory a
Math-Calculus-Expression-0.2.2 directory is created but that directory
does not have execute permissions. Presumably that is it's state inside
the .tar.gz, and also explains why CPAN hasn't indexed it.

Can the author fix this problem, or failing that, ***@cpan?

I think I already came across this problem in the past and reported it
to the author, so somone @cpan may have to step in.


Cheers,
Sendu.

I'm pretty confident that this needs to by fixed by the author. The only
other possibility would be the following chain of events:

- Jonathan doesn't react to this at all. (Not even saying he's not going
to do anything about it.) Or says he's willing to give up the module.
- You contact the PAUSE admins (***@perl.org) showing that you have
been trying to contact Jonathan by various means for an extended period
of time.
- You get the permissions to use the namespace, download the
distribution, fix it, upload with $VERSION++.

Again: This is only a fallback. Ideally, the author should fix the
distribution. I see that he's cc'd, so I suppose he'll chime in shortly.

Cheers,
Steffen
