[jasonfleming]

Attempted to build latest master branch on Frontera failed when attempting to use curl with the following error:

bash ./cloud/general/init-perlbrew.sh /work2/00976/jgflemin/frontera/production/asgs/opt/perl5
Current perl is: /usr/bin/perl
curl: option --http1.1: is unknown
curl: try 'curl --help' or 'curl --manual' for more information
