You may need to wait until your CPAN mirror catches up. (Or switch to a mirror that updates more frequently.)

As for testing, as a start, just try to install it using CPAN -- i.e. run our tests. Better yet, install and configure CPAN::Reporter first. That way, if it fails, we'll get notified automatically via CPAN Testers.

Second, try it from the command line on some libraries on your system. Pick something you know you have and pick something you know you don't have.

E.g., for me, with Strawberry Perl (Win32):

C:\david\svk>perl -MDevel::CheckLib -e "assert_lib( lib => q{m} )"

C:\david\svk>perl -MDevel::CheckLib -e "assert_lib( lib => q{jpeg} )"
Can't build and link to 'jpeg'

Or, on linux:

$ perl -MDevel::CheckLib -e 'assert_lib( lib => "jpeg" )'

$ perl -MDevel::CheckLib -e 'assert_lib( lib => "m" )'    

$ perl -MDevel::CheckLib -e 'assert_lib( lib => "iconv" )'    
Can't build and link to 'iconv'
[download]

If it doesn't give you the results you expect for those libraries, let us know, along with your perl -V output.

Thanks - I am going to test it out on AIX (xlc). I'll get back with the results once I have something for you.
