Fatal error: phpFlickr redeclared

I had the activitystream and flickrsync modules enabled and got the fatal error above.

Temp fix:
fix is you have to choose which you want for right now.

ASK:
is there anyway to see if this function is included elsewhere and only add it if it is not?

Problem: function redefinition
activitystream/activitystream_flickr/phpFlickr.php:76: function phpFlickr ($api_key, $secret = NULL, $die_on_error = false) {

flickrapi/phpFlickr/phpFlickr.php:76: function phpFlickr ($api_key, $secret = NULL, $die_on_error = false)

Thanks,
Chris
