rpm dependency missing

["Don Raikes" <don raikes oracle com>]

I am modifying the gnome-speech package for fedora core 6 to enable some additional tts engines.

I installed the cepstral swift voices (not from rpm).

I modified the gnome-speech spec file to include the swift-synthesis-driver file in the %files section.
The rpmbuild works fine, but when I try to install the rpm, I get a missing dependency of libswift.so.3.

I have added /etc/lib.so.conf.d/cepstral.conf file including a line 
/opt/swift/lib
and run ldconfig.

I rebuilt the rpm and tried to install it again but got the same message.

How do I tell rpm where this dependency lives?
