g++ compile issue

[GoogleCodeExporter]

What steps will reproduce the problem?
1. Download source using svn
2. Use "make" command to build "libtwitcurl.so.1.0" (get error messages shown 
below, but finishes build anyway)
3. Place "oauthlib.h" & "twitcurl.h" in /usr/local/include and place 
"libtwitcurl.so.1.0" in /usr/local/lib.
4. Attempt to compile attached, simple program using g++ and get error messages 
below. (all program tries to do is instantiate twitCurl object)

What is the expected output? What do you see instead?

Expected output of "make" command is clean make. Get following error messages:

Get following error messages:

Hi!
You need to link twitcurl library with your application (-ltwitcurl option). I 
have updated UNIX/Linux section in wiki page to have this info:
http://code.google.com/p/twitcurl/wiki/WikiHowToUseTwitcurlLibrary

Thanks.
