Problems building php5

[wildgoosed]

hey everyone.

i'm currently trying to re-install php5 from source on a fedora core 4 box (yes i know old). reason i am doing this from source is that i need mssql support which isn't included in the rpm i had used before.

i read that i needed to install freetds, so i downloaded the src and did the following commands...

./configure
make
make install

everything went fine with that install.

i didn't want to break any other packages that need php5 and that were currently using my rpm build of php5, so i used the configuation commands from the phpsysinfo output + the --with-mssql=/usr/src/freetds on my source install.

when i attempt to ./configure the php5 source, i get the following error...

checking for MSSQL support via FreeTDS... yes
configure: error: Could not find /usr/src/freetds/lib/libtds.a|so

[root@localhost php-5.2.3]# find / -name freetds
/usr/src/freetds

any ideas? thanks.
