Recently tried to add the Fire Eagle plugin to my MT4.21 setup, and received lots of errors. When I try to 'configure Fire Eagle' I get:
get on https://fireeagle.yahooapis.com/oauth/request_token?oauth_consumer_key=[snip] failed:
501 Protocol scheme 'https' is not supported at /var/www/vhosts/jasoncook.com/cgi-bin/mt/plugins/FireEagle/lib/Net/FireEagle.pm line 457.
and my cron job for running periodic tasks now replies:
Use of uninitialized value in localtime at lib/MT/Util.pm line 465.

It sounds like you're missing the Crypt::SSLeay Perl module, which would be required for doing "https" protocol requests.
There are lots of hits on Google for that error.
