Missing entry in php-config --ldflags

I'm having a problem. It may be very simple. I have an earlier version of php installed and I'm trying to install a newer version. In the older version the output of "php-config --ldflags" yields: -L/usr/ucblib -L/usr/local/lib/gcc-lib/sparc-sun-solaris2.8/2.95.2 -L/usr/local/openssl/0.9.7/lib -L/usr/local/lib -L/usr/local/freetds/0.62.4/lib -L/usr/local/mysql/3.23.58/lib/mysql My question is, how did they get the "-L/usr/local/lib" entry in the output? I've tried compiling it 90 different ways. When I run "php-config --ldflags" "-L/usr/local/lib" is missing: -L/usr/ucblib -L/usr/local/lib/gcc-lib/sparc-sun-solaris2.8/2.95.2 -L/usr/local/openssl/0.9.7/lib -L/usr/local/freetds/0.62.4/lib -L/usr/local/mysql/3.23.58/lib/mysql What option do you choose to get that entry in there. I'm trying to upgrade with the same compiled in options. Only thing is, I don't have that info of how it was compiled before.
