Maybe you can help us provide better solutions for the problem by telling us more about the actual problem you're trying to solve? Other than that, the straightforward approach is: `BEGIN{system("tar -xzvf XX.tar.gz")} use strict; use lib "./" use XX;` [download] ... or, according to BEGIN: `system("tar -xzvf XX.tar.gz"); use strict; require './XX.pm'; XX->import();` [download] Also see Module::Load maybe.

Have you considered packaging your script and it's dependencies, something like pp?	[reply]

By putting a code hook into `@INC` which does the decompression if the module is not already available. Then a normal `use` is enough. More details in `require` Cheers Rolf _{(addicted to the Perl Programming Language :) Wikisyntax for the Monastery}	[reply]

`use lib "./XX.pm"` Needs to be: `use lib "."` But I encourage you to look at FindBin for that sort of thing, in addition to the other help you receive here.	[reply] [d/l] [select]

Quick follow up: Is it possible to include the tar.gz file in my script as well ? Can I have only one script (packed file or something) that when i execute it, it extracts my tar.gz and calls modules within ? thnx	[reply]

That's pretty much what pp does, generates an executable which is essentially a self extracting zip file. Your method won't work on all platforms.	[reply]
