Hi jeanluca, Did you Super Search this topic before posting? It comes up quite often. Check out Finding All Installed Modules which provides some examples. Martin	[reply]

The traditionnal way is to wrap the `require` of the module in an `eval`: `if( eval "require $module") { import $module; } else { # die or apply contingency procedure }` [download]	[reply] [d/l]

I prefer just: `eval "use $module; 1" or die "or apply contingency procedure";` [download] If $module comes from an untrusted source, be sure to validate it before using in eval.	[reply] [d/l]
