:)

perl -e		: execute what I'm about to tell you 
-MCPAN 	: the module CPAN shall be loaded 
'install Perl'	: my bidding

(Although: I've been telling fibs, it should be perl -MCPAN -e 'install 
Perl', apologies - you have to give -e an argument ;)

You'll need to set CPAN up, though (usually worth it - although you're 
beginning to take things outside your package management system, I've never 
had a conflict yet. I believe the CPAN Way is different to the Debian Way, 
and hence there isn't a file conflict, which is also helped by Perl 
versioning module directories). To run CPAN for the first time, do 
	perl -MCPAN -e shell

This will lead you to interactive CPAN heaven, where you can issue your will 
and be at one with the spirit of The More Than One Way.

Ah. Either dpkg --[g|s]et-selections and piping input/output, or (*shudder*) 
dselect.

Maybe aptitude or any of the other better apt front-ends might do it, 
although apt is a bit too high level I think. I would use dpkg: you do a 
--get-selections > myfile, and then edit myfile, changing the status of the 
package from 'install' to 'hold'. Then pipe it back to --set-selections. 

Don't know any better ways :( Anyone else?? I would have thought there would 
be a dpkg --set-status hold [package], or similar, but I can't see one :(

Cheers,

Alex
