Does anyone see a problem with the following Curl call / how the Oauth request is built?
(i am trying to get a correctly setup request so i can finish my app)

So i am calling the following CURL call:

C:\>curl -v -k --data-urlencode "status=Testing2" -H "Authorization: OAuth realm='', oauth_nonce=1276107867blah, oauth_timestamp=1276107867, oauth_consumer_key=yJDLH7BDdVi1OKIINSV7Q, oauth_signature_method=HMAC-SHA1, oauth_version=1.0, oauth_signature=NWU4MDdlNjk0OGIxYWQ1YTkyNmU5YjU1NGYyOTczMmU5ZDg5

YWNkNA==, staus=Testing2 " http://twitter.com/statuses/update.xml?status=Testing2

and i recieve this:

* About to connect() to twitter.com port 80 (#0)
*   Trying 168.143.162.68... connected

  <request>/statuses/update.xml?status=Testing2</request>
  <error>Could not authenticate with OAuth.</error>
</hash>
* Closing connection #0

my Parameters are setup like so:

var parameters = [encodeURIComponent("status="+status),encodeURIComponent("oauth_token="+ac_token),encodeURIComponent("oauth_consumer_key="+"yJDLH7BDdVi1OKIINSV7Q"),encodeURIComponent("oauth_nonce="+nonce,"oauth_signature_method=HMAC-SHA1"),encodeURIComponent("oauth_timestamp="+timestamp),encodeURIComponent("oauth_version=1.0")]

var join = parameters.join("&");
var eparamjoin =encodeURIComponent(join);

The key is like so:

var key=con_secret+"&"+ac_secret;

Signature base string is:

var signaturebs = "POST&"+encodeURIComponent(url)+"&"+eparamjoin;

giving this:

POST&http%3A%2F%2Ftwitter.com%2Fstatuses%2Fupdate.xml&status%253DTesting2%26oauth_token%253D142715285-yi2ch324S3zfyKyJby6WDUZOhCsiQuKNUtc3nAGe%26oauth_consumer_key%253DyJDLH7BDdVi1OKIINSV7Q%26oauth_nonce%253D1276107867blah%26oauth_timestamp%253D1276107867%26oauth_version%253D1.0

and signature built like so:

var hmac = Crypto.HMAC(Crypto.SHA1, signaturebs,key );

var signature=Base64.encode(hmac);

making the signature:

NWU4MDdlNjk0OGIxYWQ1YTkyNmU5YjU1NGYyOTczMmU5ZDg5YWNkNA==

Any help would be appreciated thank you!
