perfsonar development work

[Loukik Kudarimoti <>]

Michalis,

Thanks for the info. I did some installation testing and came up with 
similar problems with modules.

Matthias and Mark,

My suggestion is
* specify a list of modules to be installed in perl as "requirements". 
Please add these requirements to your installation guide. We can expect 
the deployer to have these installed manually and we won't try to do it 
automatically. I say this because although we would very much like to 
take care of everything in pre-install, some things are best left to the 
administrator to install manually ( I am not convinced if using regular 
expressions will be of help in detecting missing modules)

* What you could then do is *try* to read whether the required modules 
are installed or not. You could do this in the pre-install step. If they 
are present, say "all present, pre-installation ok". If they are not 
present, you could prompt what is not present. I suppose this is easy to 
do (just do an include for all modules and errors should come up?)

The above sounds like a simple solution but please feel free to comment 
as I am not familiar with Perl.

Loukik.
