Enabling and disabling pool member (PoolMemberChangeState.pl)

Good afternoon, I'm new to iControl. I have access admin access to our F5 (Version BIG-IP 11.2.1 Build 1042.0 Hotfix HF3). I'm using strawberry perl and was able to run through all sample perl scripts that came with iControl. I had to add two lines to bypass SSL cert warning (use Net::SSL; and $ENV{PERL_LWP_SSL_VERIFY_HOSTNAME}=0;). So as my next goal, i would like to disable one of the existing pool members. I downloaded example from here: https://devcentral.f5.com/wiki/iControl.enable_disable_pool_member.ashx and again, added two lines for SSL warning that i had to add to all other sample scripts and here are the details on the command and the errors:

Execution of PoolMemberChangeState.pl aborted due to compilation errors.

Has anyone ran into the same syntax errors with this sample script? I'm going to download Perl plugin for my Eclipse next and try to look into this one.

Thank you!
