Installing dblib PDO driver

Setup: Static/CGI/PHP-5.4

I'm building an application that has a connection to a MSSQL database - I'm setting up the connection with:

$dsn = 'dblib:dbname=DBNAME;host=DBHOST';
$conn = new PDO($dsn, MYUSER, MYPASSWORD);

"dblib" being the PDO driver. However, my current setup only has these drivers installed: mysql, pgsql, sqlite, sqlite2.

After looking online, I narrowed it down that I have to install the "PDO_DBLIB" Package (Found here: http://pecl.php.net/package/PDO_DBLIB). I began following these instructions on how to install: http://atutility.com/2007/09/14/install-pdo-pdo_sqlite-pdo_dblib-pdo_mysql. After the build command was entered, it printed this with an error at the last line:

So now my new task is getting FreeTDS installed. I got the .tgz file from its website, unpackaged it, put the folder on my server, cd'd to the folder and ran:

$  sh ./configure

This command fine. Based on the Installation instructions within the folder, the next step was to run "make". I entered this and it returned this error:

$ make

and that's where I'm stuck. I've been looking everywhere on how to resolve this but haven't found anything helpful. So my questions are either: How can I fix this FreeTDS installation error? OR What's an alternative way I can get the dblib driver installed?

I would greatly appreciate any answers, guesses, tips, etc. Thanks much!
