[Theme: Blaskan] Instagram widgets?

Trying to pull in Instagram photos into sidebar. Downloaded the Instagram Gallery Widget and Instagram for WordPress and couldn’t get either to work in Blaskan. Using Scherzo, the Instagram Gallery Widget is working, but not Instagram for WordPress. The instructions on Instagram for WordPress say “Requires PHP curl extension” but not sure which extension that would be, after searching.
