Dave,

>Do I detect a hint of annoyance there?

No, not at all.  I was trying to indicate that I had been paying careful
attention to who had downloaded the ldm-mcidas distribution and who
had not.  Since I saw that you had downloaded it, I left you off my
list for personal contact figuring that you either had already done
the preparations or were ready to.

>Can I blame you?

I was not annoyed, really.

>I stayed more or less on top of all the warnings and emails exchanged

In reviewing my download logs, I see that you grabbed the source
distribution.  Is there a reason that you did not grab one of the
binary distributions that I made available?  I think I remember that
your LDM is running on a Sun SPARC system, and I made binaries
available for the 5.6, 5.7, and 5.8 releases of Solaris SPARC.

Right.

Satellite images are the only things left in the Unidata-Wisconsin
(MCIDAS feed type for the LDM) datastream.  All of the other data was
removed in July of 1999.

>I eventually concluded (incorrectly, obviously),

Oops :-)

>Could you confirm that I have to install MCIDAS to install the
>ldm-mcidas decoders (in particular, pnga2area)?

Only if you need to build the decoders.  What OS is your LDM running on?

>If that wasn't the problem, I'll try installing ldm-mcidas again and
>report the details of the problem I was having.

That was the problem, but I feel certain that we should have a binary
that will work for you.
