CPAN won't install a module if it's not compatible with your perl version. If the module requires 5.10.1, it'll tell you and stop. What's more important to me is the minimum version of perl. For example, Perl::MinimumVersion requires a minimum of 5.006, so you can check it like this:

#!/usr/bin/perl -l

use strict;
use warnings;
use Perl::MinimumVersion;

my $obj = Perl::MinimumVersion->new(
    "/usr/local/share/perl5/Perl/MinimumVersion.pm",
);
print $obj->minimum_version;

Unfortunately, it only works with files on your disk: files, scripts, code, modules, etc.

• Are you posting in the right place? Check out Where do I post X? to know for sure.
• Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:

  <code> <a> <b> <big> <blockquote> <br /> <dd> <dl> <dt> <em> <font> <h1> <h2> <h3> <h4> <h5> <h6> <hr /> <i> <li> <nbsp> <ol> <p> <small> <strike> <strong> <sub> <sup> <table> <td> <th> <tr> <tt> <u> <ul>

• Snippets of code should be wrapped in <code> tags not <pre> tags. In fact, <pre> tags should generally be avoided. If they must be used, extreme care should be taken to ensure that their contents do not have long lines (<70 chars), in order to prevent horizontal scrolling (and possible janitor intervention).
• Want more info? How to link or How to display code and escape characters are good places to start.
