Not posting to LinkedIn ... undefined stuff

In watchdog, I see these four errors with each failed attempt to post to LinkedIn:

1) "Undefined variable: request"
file: /var/www/sites/crimdef2/sites/all/modules/linkedin/linkedin.inc, line: 413

2) "Undefined index: error"
file: /var/www/sites/crimdef2/sites/all/modules/linkedin/linkedin.inc, line: 184

3) "Undefined index: error"
file: /var/www/sites/crimdef2/sites/all/modules/linkedin/linkedin.inc, line: 184

4) "Undefined variable: base_url"
file: /var/www/sites/crimdef2/sites/all/modules/linkedin/linkedin_status/linkedin_status.pages.inc, line: 153

I am seeing no other errors, either posted to the screen or in watchdog.

I have activated "debug mode" in the LinkedIn Integration settings, but there's no additional info that I can find.

Thoughts? Thanks.
