Since you're not using strict 'refs' 
~ $ export module='JSON::PP'; perl -M$module -e 'print ${$ENV{module}.
+"::VERSION"}'
4.07~ $
~ $

Next time please use code tags instead of pre .

Edit

Or just use the VERSION method 

~ $ export module='JSON::PP'; perl -M$module -e 'print $ENV{module}->V
+ERSION'
4.07~ $
~ $

  • Titles consisting of a single word are discouraged, and in most cases are disallowed outright.
  • Read Where should I post X? if you're not absolutely sure you're posting in the right place.
