Movable Type 4.1 Works Great - Plugin's Will not Install CGI Error, Help?

I get the following error:

CGI ERROR The specified CGI application misbehaved by not returning a complete set of HTTP headers.

As soon as I remove the plugin files from their directories, everything works just fine again.

The paticular plugins I am trying to utilize are as follows:

MT-Hacks User Profiles Visitor Stats Instant Video

All of which look to be listed as compatible with MT4. Any help would be appreciated.

Here is my mt-check.cgi output:
