Hi Frank,

Sounds good!

We believe that this will be a valuable experience for your student going
forward.  Our experience is that students who graduate with more than a
cursory understanding of computers (and operating systems, and programming,
etc.) are much more valuable-in today's workplaces.

Typically when installing Linux, one is given the option of installing a
full development environment.

Question:

- how was CentOS installed?  What I mean is:

  - was it installed from a set of CDs
  - was it installed from a DVD
  - was it installed over the net

Give the early nature of the effort there, I would suggest that
the easiest/quickest course of action right now would be to drop back
and do the installation over again, but this time choose to install all
development packages.  This may seem like a lot more work, but it will
save a lot of time and effort in the long run.

It is, but the fact that gcc wasn't installed alerts me to the liklihood
that a number of other packages that will be needed later are also not
installed.  It would be _MUCH_ easier at this point to reinstall CentOS
from source, but this time choose to install all development packages.

> but I wondered if we can use one of the pre-compiled binaries?

We do not make the LDM available in pre-compiled binary form.  The main
reason for this is that the LDM is by nature a highly optimized package
that needs to be built in the environment in which it will be run.

I am not sure what list you are looking at.  Again, the LDM is not made
available in any way other than as source code that needs to be built on
the machine on which it will be run.

Just so you know, we are happy to help you to get your machine setup after
the OS is loaded, security setup, and connected so that it is accessible over
the Internet.  Please let us know if you would like us to help.

> thanks,

No worries.

Cheers,

Tom
