server configuration in freetds.conf doesn't appear to be available in PHP

Hello All,
I am trying to get freetds up and running in PHP 5.3.2 on Apache 2.2.14.  I have downloaded the latest snapshot and ./configured it.  Using tsql I am able to connecto to my SQL Server instance using the -S option so it appears that freetds is recognizing the server configuration.  However, when I try to call mssql_connect in PHP with the alias for my server it fails (no error message, it just returns false).  When I specify the DNS name for the server then mssql_connect call works just fine.  I tried editing the freetds.conf file to turn on logging but no log file appears in the /tmp directory.  I also tried explicity setting the TDSDUMP and TDSDUMPCONFIG environment variables but the log files are not created when I call mssql_connect from my PHP page.  I also tried setting the FREETDS en
 vironment variable to point to my freetds.conf file without success.
Getting the PHP info from the webserver shows under a mssql heading:Active Persisten Links 0Active Links 0Library version FreeTDS

Any help would be greatly appreciated.
Thanks,--Ben
